#326 Re: Other Issues » Chromium after upgrade - Jessie to Ascii » 2018-04-06 19:24:04

Hi, Geoff42. I'm on a fully up-to-date ASCII here. I mostly use firefox but do have chromium 64.0.3282.119-1~deb9u1, which I use as a backup browser. I installed ASCII from scratch and didn't have to do anything special to get that version of chromium. I have never had this version of chromium give off any errors or ask me to reload, not even when using Google maps.

Hopefully it will be smooth sailing for you and the error will not return. If it does, I will be happy to try to help.

#327 Desktop and Multimedia » how to customize volume osd icon? » 2018-04-06 18:30:55

Replies: 0

This is just out of curiosity. I noticed that without compton compositor running, this is the icon I see when I press the volume buttons on my laptop:

without_compton.png

When compton is running, the icon changes to this:

with_compton.png

I was surprised by the change and was wondering why the icons are different and how to customize them. Any ideas? Duck-ducking did not turn up anything useful.

P.S. I'm on on ASCII with MATE 1.16.2. My WM is MATE's default (marco).

#328 Re: Desktop and Multimedia » trailing artifact when moving icons around MATE's desktop [SOLVED] » 2018-04-06 00:55:33

Right on, golinux!

If I turn on marco's compositing, issue gets much better. If I leave marco's compositing off, install compton, and add compton to my startup applications (command=compton -bCG), problem goes away completely.

This is strange because in Devuan Jessie I run marco with compositing off and have no issues.

(This is yet another way in which MATE is dropping the ball. I shouldn't have to turn on anything special in order to avoid weird glitches when doing something as simple as moving an icon on the desktop...)

#329 Re: Desktop and Multimedia » trailing artifact when moving icons around MATE's desktop [SOLVED] » 2018-04-05 20:57:29

I'm talking about the weird, ghostly icon that moves between the original location and new location. It happens when I drop the icon at the new location. You can see it in the video.

This is definitely not something I've seen in MATE before. Given the erratic nature of this (only part of the icon shows up in the blur, bits and pieces of the desktop background fly away and back, sometimes it does not happen at all) I'm pretty sure this is a bug.

This is not a big deal, of course, but if one of you smart guys has an instinct of what could be causing this (or know for a fact what is causing it), I'd like to try fixing it.

I've been squashing bugs on my ascii partition for a few weeks and have finally gotten to the last obvious one. This is just a  cosmetic issue, but it irritates me.

I use my desktop as a workbench and frequently have multiple files on it when I'm working on a project. Part of my workflow often involves rearranging the icons so that files are grouped in ways that make sense to me. Unfortunately, on ASCII with MATE 1.16.2 and caja 1.16.6-1+deb9u1 it is a bit freaky to drag an icon to a different location of the desktop because most of the time it leaves a ghostly trailing artifact behind it. Here is a video that shows what I'm talking about:

http://files.dantas.airpost.net/public/ … tifact.mp4

The issue occurs on all kernels I've tried. I tried upgrading just caja to the version in ascii-backports (1.18.5-2~bpo9+1) and the issue was still there. I'm back on the default version now (1.16.6-1+deb9u1). This issue did not occur in Devuan Jessie with MATE.

Is anyone else having this issue with their desktop icons? Any idea how to begin troubleshooting this?

#331 Re: Hardware & System Configuration » trying to understand basics of SysVinit scripts [SOLVED] » 2018-04-03 13:00:05

The missing step was to add test to the end of the TARGETS list at the top of /etc/init.d/.depend.start

At this point I don't understand why it worked, but am happy to be one step closer to understanding.

Thanks again!

#332 Re: Hardware & System Configuration » trying to understand basics of SysVinit scripts [SOLVED] » 2018-04-03 12:46:24

Thank you, ralph.ronnquist. I guess nothing is ever as simple as it seems.

I will learn about insserv and friends, and will experiment with the hidden files. I have a full partition backup, so I can tinker with abandon.

I'll update the thread if there is a simple solution to my little exercise. If it's too complicated, it kind of defeats the purpose.

This is a super basic exercise that has me stumped. Please help and pardon my ignorance.

1. I created /etc/init.d/test with this in it:

#!/bin/sh

touch /home/bruno/Desktop/hello

Then I made the script executable.

2. I ran this command: sudo ln -s /etc/init.d/test /etc/rc2.d/S09test

3. I reboot the system.

The script does not appear to run (i.e., a file named "hello" does not show up on my desktop). What am I missing?

P.S. I do not want to use LSB headers or the update-rc.d command. I can get things to work that way, but for this exercise I want to do things manually and as simply as possible so that I can understand the absolute bare essentials.

Freezepop is also very good: Lazy.

#335 Re: Hardware & System Configuration » occasional boot hang on ascii [SOLVED] » 2018-03-31 16:48:38

So far, so good with linux-libre kernel 4.15.14, which I got from here: http://linux-libre.fsfla.org/pub/linux- … ol/main/l/

No graphics glitches with this kernel, and so far no hung boots. Too early to tell if hung boots issue is solved given that it only happens once in a while, but I will be optimistic and will try (again) marking this issue as solved.

If I don't post again, it's because the hung boots went away.

#336 Re: Hardware & System Configuration » occasional boot hang on ascii [SOLVED] » 2018-03-31 15:27:28

This sounds somewhat like my issue:
https://bugzilla.kernel.org/show_bug.cgi?id=82481

Since this issue may be related to kernel 3.16 and all of 4.9, 4.13, and 4.14 were giving me graphics artifacts, I'll try my luck with 4.15 and will report back.

#337 Re: Hardware & System Configuration » occasional boot hang on ascii [SOLVED] » 2018-03-31 14:00:52

Problem happens sometimes with startx as well. At least startx produces a (helpful?) error message when it happens:

screenshot.jpg

The interesting bit is "intel_do_flush_locked failed: Invalid argument" of course. I did some duck-ducking and it sounds like this could be a kernel bug. If so, this is extremely strange because I'm running the same kernel in ascii that I was running in jessie without any issues (I'm using the older kernel 3.16.51-3+deb8u1 because ascii's default kernel causes some graphics artifacts on my machine: https://dev1galaxy.org/viewtopic.php?id=1905).

#338 Re: Hardware & System Configuration » occasional boot hang on ascii [SOLVED] » 2018-03-31 04:10:50

So far so good with startx. Here's what I did:

1. sudo apt-get install xinit (the xinit package contains the startx executable)
2. sudo apt-get purge lightdm
3. In /etc/inittab, comment out this line: 1:2345:respawn:/sbin/getty 38400 tty1
4. In /etc/inittab, add this line for autologin: 1:2345:respawn:/bin/login -f bruno tty1 </dev/tty1 >/dev/tty1 2>&1 (use your username instead of bruno, of course)
5. To run startx automatically upon login, add startx to ~/.profile

Hopefully the miscommunication between X and display manager (i.e., X sending a signal that it is ready for lightdm/slim to connect when it isn't actually ready) does not happen between X and startx. I'll mark as solved for now. If problem recurs I'll post again and remove the "solved" tag.

#339 Re: Hardware & System Configuration » occasional boot hang on ascii [SOLVED] » 2018-03-31 01:29:35

Problem just recurred despite 1-4 in post #20.

I'm giving up on getting X and a display manager to consistently play nice. Will try my luck with startx, hopefully it will be more consistent.

#340 Re: Hardware & System Configuration » occasional boot hang on ascii [SOLVED] » 2018-03-31 00:23:28

Thanks, ralph.ronnquist. Inserting a delay between X's ready signal and lightdm's connection attempt sounds like a promising hack, but beyond my (current) skills.

I also thought of downgrading X to the version from Devuan Jessie, which apparently never signaled before it was actually ready for incoming connections. I'm trying the downgrade now but am quickly finding myself in dependency hell.

#341 Re: Hardware & System Configuration » occasional boot hang on ascii [SOLVED] » 2018-03-30 14:51:50

Thanks, catprints. I did it just now and everything was checked.

So a recap of where I am at this point:
1. Tried using slim instead of lightdm, but problem recurred so I'm back on lightdm.
2. Uninstalled consolekit. Problem recurred afterwards but I'm leaving consolekit uninstalled since it seems superfluous.
3. Ran pam-auth-update as root. Everything is checked in the prompt.
4. Did full system upgrade again this morning.

I'll update the thread when I have something new to share.

#342 Re: Hardware & System Configuration » occasional boot hang on ascii [SOLVED] » 2018-03-30 12:46:41

No luck. Problem struck again first boot this morning. Uninstalling consolekit was not the answer.

#343 Re: Hardware & System Configuration » occasional boot hang on ascii [SOLVED] » 2018-03-30 04:06:44

fsmithred and golinux, thank you both very much. Based on the simple word or in fsmithred's post and golinux's link, I realized that I don't need both consolekit and elogind.

I tried uninstalling elogind (to simulate the package lineup in my problem-free Devuan Jessie partition) but doing so would force the removal of a truckload of packages including most of MATE. Therefore, I uninstalled consolekit. So far no negative consequences and I've booted my system 20 times for testing without any "hung" boots so far (using lightdm from ascii's repo). Fingers crossed...

fsmithred, is it possible that the intermittent nature of my issue was because of a race condition between elogind and consolekit?

#344 Re: Hardware & System Configuration » occasional boot hang on ascii [SOLVED] » 2018-03-30 03:12:25

Hi, fsmithred. Thanks for piping in. All these packages are installed on my ASCII partition:

Packages with 'libpolkit' in name:
libpolkit-agent-1-0:amd64 0.105-18+devuan2.4
libpolkit-backend-1-0-elogind:amd64 0.105-18+devuan2.4
libpolkit-gobject-1-0-elogind:amd64 0.105-18+devuan2.4
libpolkit-qt-1-1:amd64 0.112.0-5
libpolkit-qt5-1-1:amd64 0.112.0-5

Packages with 'consolekit' in name:
consolekit 0.4.6-6

Packages with 'elogind' in name:
elogind 234.4-1+devuan1.5
libelogind0:amd64 234.4-1+devuan1.5
libpam-elogind:amd64 234.4-1+devuan1.5
libpolkit-backend-1-0-elogind:amd64 0.105-18+devuan2.4
libpolkit-gobject-1-0-elogind:amd64 0.105-18+devuan2.4

I honestly know very little about these packages, so don't know why these particular ones are installed.

These are the only packages on my Devuan Jessie partition, which always boots reliably:

Packages with 'libpolkit' in name:
libpolkit-agent-1-0:amd64 0.105-9+devuan1
libpolkit-backend-1-0:amd64 0.105-9+devuan1
libpolkit-gobject-1-0:amd64 0.105-9+devuan1
libpolkit-qt-1-1 0.103.0-1

Packages with 'consolekit' in name:
consolekit 0.4.6-5

Packages with 'elogind' in name:
none

Problem recurred with slim. Darn. I guess lightdm is innocent.

I'll try the other things but am running out of hope of nailing down this issue.

#346 Re: Hardware & System Configuration » occasional boot hang on ascii [SOLVED] » 2018-03-29 21:02:36

I will give slim a try. If problem recurs with slim, then maybe xorg is to blame? I still think ntp is a red herring, but will try disabling it if all else fails.

golinux might be on to something. I rebooted several times and it happened again after a handful of boots. This time I saved the entire /var/log directory.

I marked the first line that's different between the two lightdm logs with some asterisks.

Before I jump ship and switch from lightdm to slim (which I've never used), I'd like to try troubleshooting my system as currently configured. Maybe lightdm is innocent and this is actually an X issue despite the benign-appearing X log?

Any idea why lightdm is failing? Now I have access to whatever logs we need.

P.S. I tried bbatten's idea but no luck. When boot hangs this way, computer does not respond to anything except power button and SysRq key.

#348 Re: Hardware & System Configuration » occasional boot hang on ascii [SOLVED] » 2018-03-29 18:33:45

bbatten, that's an interesting idea. I will try that next time I have the issue and will post the result in this thread. I do know that at least the kernel is running (SysRq key works and I can use it instead of power button to reboot).

Also, FWIW the problem affects all virtual consoles: When screen is black and I press Ctrl+Alt+F1 (or F2, F3, etc), instead of seeing a login prompt like I normally do I just see the same totally black screen.

Next time it happens I'll save the X and lightdm logs in addition to syslog.

#349 Re: Hardware & System Configuration » occasional boot hang on ascii [SOLVED] » 2018-03-29 18:01:33

I just had another hung boot. It was 1:42 pm when the boot process left me at the black screen. I waited at the black screen until 1:46 pm before forcing a reboot with SysRq keys. These are the last few relevant lines from /var/log/syslog. I can go further back if necessary:

It seems that the last lines logged from the boot attempt were from ntpd, but maybe that's a red herring. Any ideas?

#350 Re: Hardware & System Configuration » occasional boot hang on ascii [SOLVED] » 2018-03-29 17:32:39

I use MATE with its default WM, which is marco. My display/login manager is lightdm.

I took a look through /var/log/syslog but did not find anything obvious yet.
