Watch for a problem with xserver-xorg

[mld]

same here. Dell Lat. e6540 with Intel gpu.

As a workaround you can switch to plasma-wayland. Your mileage may vary, though, because with wayland things like redshift, vbox, telegram-desktop, drag'n'drop or similar  might not work as expected.


It's worth trying to start  these apps with the "-platform xcb" parameter, but it might fail as well.

Same here.
SAtarting until sddm is okay, then a lot of flickering is happening on the screen. plsma is opening here, so no freeze, but unusable due to flickering.
A partial workaround is to open Screensettings (Anzeige) and choose a smaller resolution, confirm, and then again the right solution (confirm agein).
Programs work, computer is usable, but plsama is dead. No working Kmenu or working icons.

mh, didn't read the warnings  , so I had the same issue as drooghead, freezed panel (plasma/kf5 & intel graphics) and so on programs working using the kernel modesetting driver.
I switched temporary back to the intel-driver (xserver-xorg-video-intel) and all works fine again.

Yesterday I got a problem that maybe are related to this. After d-u with no warnings no removes I can't get in to XFCE anymore.After login I can see the blue background where itś written "draft" and then I'm dropped back to login screen.
The difference from other machines working after d-u this has a nvidia graphic.

I had problems with plasma, xfce, plasma-wayland and lxqt. I downgraded xserver-xorg-core with xserver-xorg-core_1.19.6-1_amd64.deb from debian snapshots and both my machines appear to be working properly again.

how did you switch?


Thanks

[hendrikL]

How did I switch?

if you have the "xserver-xorg-video-intel" driver installed it is easy.

Code Auswählen Erweitern

cp /usr/share/doc/xserver-xorg-video-intel/xorg.conf /etx/X11/

restart the xserver and all done.

Code Auswählen Erweitern


cat /etc/X11/xorg.conf

Section "Device"
        Identifier "Intel"
        Driver "intel"
        Option "AccelMethod" "uxa"
EndSection


That is my xorg.conf, most systems don't need  that 'Option "AccelMethod" "uxa"' so let the original as it is.
I have made it for my old ancient system, the first time it had problems with the modesetting driver so i used the old-dusty-dead-horse-intel-driver to have a working laptop.

Be aware ,that it is not the recommended  way to use the intel-graphic!

Did you tried  to downgrade like drooghead wrote?
I am to lazy to do it, because i have that xorg.conf that is all.

In case of problem i can confirm that a downgrade with https://packages.debian.org/it/buster/amd64/xserver-xorg-core/download fix the issues

[vilde]

I had problems with plasma, xfce, plasma-wayland and lxqt. I downgraded xserver-xorg-core with xserver-xorg-core_1.19.6-1_amd64.deb from debian snapshots and both my machines appear to be working properly again.

I cant fin a working way to downgrade, how shall I do that? I downloaded the file but it will not install because of dependency problems (of cause).

Edit: sorry, I did it with dpkg, that was to easy so I didn't try it before, I thought I have to do it with apt some way, I got it working for now

Yes the file is no problem to find but I can't install it.

System works again as desired?

In my case, the hendrikL solution has fixed this problem.Thanks hendrikL.
