I’m on a laptop with openSUSE Tumbleweed, LVM encryption and KDE Plasma. Sometimes the graphics just completely freezes, and I need to kill the Server. It seems like stuff keeps running, it’s just the graphics that freezes. I don’t find any messages in Xorg.0.log from when it happens.
Hello i have a laptop with intel 2gen HD3000, and the bug/glitch/error is not external graphics cards is the it-self dedicated card and the solution that i find was this
- Go /etc/X11/xorg.conf.d/
- Create 20-intel.conf
- Put:
Section “Device”
Identifier “Intel”
Driver “modesetting”
Option “AccelMethod” “glamor”
Option “Backlight” “intel_backlight”
[LIST=1|INDENT=2]
[/LIST]
EndSection
i dont know why the ppl of kde fix a bug to enter to other, because in the 5.8 early versions, this error not exist and the 5.7 neither have this error, i am using leap 42.2 KDE 5.8.x, other solution i try and work too is change opengl 2.x v to opengl 3.xv
if you want a fix you should give more information. what processor/graphics you have.
In my search, the intel graphics is which create the freeze situation
the backlight option should be commented out if you’re using the xorg modesetting driver instead of the intel … IOW, its an xorg intel driver option, not one (currently) applicable to the modesetting driver … see “man intel” and “man modesetting” for details
I’m not sure using glamor is the best solution, if your dual gfx system is not optimus set the external card as the preferred and install it’s drivers (nvidia or ati) (ask google)
there is a known bug with plasma 5 and the intel driver which is in the process of being fixed, the solution is to use uxa acceleration

create the file /etc/X11/xorg.conf.d/20-intel.conf
kdesu kate /etc/X11/xorg.conf.d/20-intel.conf
and paste this
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
I have an Intel Core-i5 3230M (Ivy Bridge) with Intel HD graphics 4000
I’ll try that.
Hello, i try this config, and set opengl 3.1 and fix the freeze, thank for this better solution.
