The timeout is a day, or 86400 seconds, since the creation of the post.

@Vernon, it shouldn't have stopped you from editing that post so I'm not sure what is happening there.

'edit' and 'delete' are treated the same based on my reasoning that editing lets you remove all content, and a blank post is basically the same as a deleted post.

@GNUser: please note that R2 is an off-the-shelf router (TL-WR841N) and it offers only an http(s) admin panel rather than shell access.

@Devuman: with forwarding set up, you should use only

ssh <PC1user>@192.168.18.8

That's the whole idea of forwarding. It makes R2 to channel tcp connections on its port 22 WAN side (ie 192.168.18.8:22) onto port 22 on PC1 (ie 192.168.1.101:22) without involving itself in the traffic.

The double-hop is used when you have ssh access to an intermediate host, to use that as a temporary forwarding channel.

If the ISP has port 22 closed outside of R1 then you probably need to contact them to open it. But that's only to get access to PC1 from the Internet.

The R1 virtual server set up you show on the screenshot makes it possible to access port 22 on PC1 from the Internet, provided that R2 is set up similarly, and that it has that IP address 192.168.18.8 mentioned on the screenshot as its WAN side IP address.

sftp access from LT2 to PC1 only requires the R2 set up (not the R1 set up), and PC1 would then be accessed using that same IP address.

Might you have forgotten to do

apt-get update

as well, so as to update your local package lists?

It's not clear to me what "delete this account" means to you, but I've now disabled access by that userid.

Great. Give me another day or two to pack up and send you the phrase tables.

Firstly you might test by using ctrl-alt-f1 to shift to VT-1 and log in as root. Does that result in the same experience as your su --login, i.e. blank password is fine, and then bash complains about ash?

hmm I think I missed yours @haroldG75, did I? ... Let me collate the basis and email it to you both, and you coordinate who does what of it.

Hmm for me it is like:

stolpe% wmctrl -l
0x01000004 -1 stolpe xfce4-panel
0x01200003 -1 stolpe Desktop
0x03000003 -1 stolpe 
0x03400010 -1 stolpe logs - ralph.ronnquist@realthing.com.au - Mozilla Thunderbird
0x030010c7  0 stolpe 
0x02e00003 -1 stolpe gworldclock
0x030013d8  0 stolpe files
0x0360007f  0 stolpe desktop / workspaces / Off-topic / Dev1 Galaxy Forum - Pale Moon
0x0300341e  4 stolpe hello
0x03200003  4 stolpe Xfburn
0x03a00017  3    N/A TkDiff 4.1.4

It appears the second column is the _NET_WM_DESKTOP property of the windows; "-1" means that the window is to be shown on all workspaces, and otherwise it's the workspace where the window is shown. At that time, my monitors show workspace 0.

This is not cinnamon though; it might use some other window property, or it might keep that information elsewhere. The use of _NET_WM_DESKTOP property is in the wm-spec "standard", e.g. at https://specifications.freedesktop.org/ … 6085202544
but there's no compelling reason for cinnamon to  adhere to that standard.

@toru, what does cat /sys/class/backlight/acpi_video0/max_brightness say?

Presumably something less than 100, as according to your post #7, the complaint was about the value, not the writing.

If that's the case, you should try again with @Head_on_a_Stick's tee method and a number between 0 and that maximal number. Ideally half of max should result in 50% brightness.

Would you mind explain what using a hd-media method means with respect to install a devuan_beowulf_3.0.0_i386-netinstall.iso ?

In my mind you either use devuan_beowulf_3.0.0_i386-netinstall.iso or that which you find under https://pkgmaster.devuan.org/devuan/dis … nt/images/. They are two different and separate approaches to use for achieving a situation where you have Devuan installed.

I can understand if one of them, or both, have problems dealing with some hardware (even though at a glance your hardware seems far from obscure) but I'm afraid I can't immediatly understand how to conflate the two installation approaches into one.
