Refracta problems on Ideapad laptop

I was planning to install Refracta 11.2 on a Lenovo Ideapad S210 Touch "netbook"; however, after the live system fully loads the touchpad and keyboard do not work at all. A USB mouse that I plugged in works, so that's an acceptable temporary workaround for the nonfunctional touchpad, but I still need a working keyboard to use the installer.

I also tried SystemRescue (formerly SystemRescueCD). With SystemRescue, the touchpad is also nonfunctional, but the keyboard works just fine. With a USB mouse plugged in, I was able to prepare the HDD by deleting all of the Windows partitions.

Anyone have any ideas as to how I should proceed?

Re: Refracta problems on Ideapad laptop

Hello:

... Refracta 11.2 on a Lenovo Ideapad 210 Touch ...
... touchpad and keyboard do not work ...
... With SystemRescue, the touchpad is also nonfunctional, but the keyboard works just fine.

Seeing that System Rescue actuallu finds the keyboard, look at what its logs have to say about it:

~$ sudo dmesg | grep -i keyboard

As to the touchpad, see what x11 has to say:

xinput list   #if you don't have it you need to install it:

sudo apt install xinput

Please post your findings.

Best,

A.

Re: Refracta problems on Ideapad laptop

Hello:

Thank-you.

You're welcome.

#1:

# dmesg | grep -i keyboard
[   13.000115] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input8
[   22.030425] ideapad_acpi VPC2004:00: Keyboard backlight control not available

Right, there is the working kb, as seen by SystemRescue.

#2:

# xinput list
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ PixArt USB Optical Mouse                	id=10	[slave  pointer  (2)]
⎜   ↳ ELAN Touchscreen                        	id=11	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Power Button                            	id=6	[slave  keyboard (3)]
    ↳ Video Bus                               	id=7	[slave  keyboard (3)]
    ↳ Power Button                            	id=8	[slave  keyboard (3)]
    ↳ Sleep Button                            	id=9	[slave  keyboard (3)]
    ↳ Lenovo EasyCamera : Lenovo Easy         	id=12	[slave  keyboard (3)]
    ↳ Ideapad extra buttons                   	id=13	[slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard            	id=14	[slave  keyboard (3)]

There is the PixArt USB Optical Mouse and what SystemRescue sees as a touch screen.
I assume that there's no such thing, just a touchpad.
Right?
 
I've had a quick look around and it seems that the Elan touchpads are a rather troublesome thingy for Linux.

Please do this:

sudo dmesg | grep -i elan to see *if* dmesg has something to say about the touchpad.
and
cat /var/log/Xorg.0.log | grep -i "input driver" to see what driver SystemRescue uses for the kb and post the results.

Best,

A.
