Mint 17.3, KDE4

On Friday, I was playing a game and my video card popped and caught fire. Crazy night. My system shut down immediately when the card went out. Anyway, I just got my system set back up temporarily on integrated graphics.. when I got back into Mint for the first time, I was given a message at the top of the login screen saying something like "continue to wait or press s to skip mounting or m for manual recovery". I hit S.. I think. I stupidly just kinda whizzed though it thinking things would be fine.

Anyway, I get back into KDE and all sorts of things are broken.

* All of my windows are missing titlebars. It's just the application menu at the top (file/edit/etc).
* I get a resize cursor when I hover over the edge of a window, but I can't resize any windows.
* Typing doesn't work at all.. it works when I enter my password at login in MDM.. but nowhere else.
* I get minimize/maximize/exit buttons in Chrome, but they're completely nonfunctional.. pressing them does nothing.
* Application buttons are not showing up in my task bar when I launch something.
* Most new programs I open start up at 0,0 on my screen (top-left corner), despite me having KDE configured to start up all programs center screen.

I'm completely at a loss here. Any idea what could be screwed up or how to repair it? This seems to be related more to KDE than anything else.. but I suppose I could be wrong.

I would guess its your graphics drivers, but no within my knowledge base

you should post what the card was that died and the integrated graphics now used. I would try reinstalling the drivers

in Konsole run

Code: Select all

kwin_x11 --replace

there should be errors

I'll try that when I get home from work, thanks. Video card was a GTX 780, integrated graphics is Intel HD 530 on a i7-6700k. Do you really think graphics drivers could cause all of those weird issues?

I never switched drivers when I booted back into Mint. I couldn't do it from the driver manager anyway since I am unable to type my password in.. so I'll have to drop into a TTY session I suppose.. hopefully those keys work... . If not, maybe I can mod the grub params for it

either that or a bad upgrade

remove the Nvidia drivers and then reinstall the Intel ones, maybe the system is still loading the Nvidia drivers and using them

I will give it a shot, thank you.

So it's been a couple days.

I tried out

Code: Select all

kwin_x11 --replace

from a TTY session and it was saying command not found. Maybe I did it from the wrong one?

I also tried setting grub parameters for intel graphics (i915.modeset=0) and that didn't have any effect either. I couldn't figure out how to install intel drivers from the command line. It seems intel supplies a tool to install the drivers, but it's a gui tool.

Unless someone has any other suggestions, I'm probably just going to hold out until my new video card arrives in a week or two and continue to boot into Windows.

kwin_x11 command won't work in a tty session, you need to run in in Konsole when you're in you broken KDE session

Figured as much. Problem is, from my original post, I can't type. That's the biggest part of my issue. It responds to some hotkeys, like ctrl+alt+f1 worked fine to enter tty.. but no text input is received into any application. Which also means I can't run anything that asks for a password.. so I couldn't open my driver manager or anything.

So I can open Konsole, but I can't do anything with it

Ah-HA... I might be onto something here.

I booted back into Mint and tested out Konsole. I indeed cannot type into it... but my system info script revealed some info.

It says WM Not Found, and that my GPU is "Gallium 0.4 on llvmpipe", whatever that is.



I am able to paste text into Konsole. I typed the kwin_x11 command in a browser (firefox and chrome are only programs that will accept text input), and copied it and pasted it into Konsole along with a new line chraracter to execute it. It still says command not found. Something seems borked with kwin

rally no ideas about this stuff

if this is the script you ran (https://gist.github.com/DennisLfromGA/7829243) then the "wm not found" means there is no window manager (including kwin) currently running

try reinstalling the xserver-xorg-video-intel pkg after uninstalling the nvidia drivers

Ok thanks. I tried

Code: Select all

sudo apt-get remove --purge nvidia-*
sudo apt-get remove --purge xserver-xorg-video-intel
sudo apt-get install xserver-xorg-video-intel

Rebooted. Thankfully I didn't break anything doing that But I'm still in the exact same situation.

I'm out of ideas.

maybe you're config got corrupter, try creating and logging in as a new user https://askubuntu.com/questions/643411/ ... g-features

other option would be to reinstall all the kde packages

Hello,

The message about libEGL.so.1 not being found is important. That file can come from both the NVIDIA driver or libegl1-mesa, so try to reinstalling the latter:

Code: Select all

sudo apt-get remove --purge libegl1-mesa
sudo apt-get install libegl1-mesa

After that, KWin might work, so try to launch it:

Code: Select all

kwin --replace &

If this doesn't work, you can also try removing any xorg.conf:

Code: Select all

sudo rm /etc/X11/xorg.conf

Then try again with KWin.

If KWin still doesn't work, you can get back keyboard input. Just install some random window manager, for sample Openbox:

Code: Select all

sudo apt-get install openbox

Then, just start Openbox (from within a graphical session) with:

Code: Select all

openbox --replace &

You should get window decorations. Post here any error message from KWin.

Louis

Thanks so much Louis!

You got Kwin back up for me, I did have some issues though. When I removed libegl1-mesa, it wanted to remove a lot of other packages. I went ahead and said yes, and none were added back in when I reinstalled mesa. I'm not sure which ones I should reinstall manually. I had to manually reinstall kde-window-manager, and it was then that my desktop popped back into existence

I also get quite a few errors running kwin --replace & (some of this could be due to me having Skylake and an older kernel; 3.19 - I read something about that HERE)


sudo apt-get remove libegl1-mesa

From what you posted, I think you need to reinstall the following:

Code: Select all

kde-workspace obs-studio openra pithos totem totem-mozilla totem-plugins-extra xserver-xorg-video-ati xserver-xorg-video-glamoregl

You still don't have HW acceleration. Try the GRUB parameter from the Arch wiki, or install a backported version of the driver: xserver-xorg-video-intel-lts-wily should be much more recent.
