KDE Freezes randomly and only the mouse pointer works

[I_A]

@mder

Hi,

I experience the same problem : after a few hours of work, desktop freezes and only the mouse seems to react. Any clic, anywhere does nothing. I can ctl+F1 and log in on text console and top but no process seems to overrun… The only solution is to halt system and reboot.

I first tried, as sugested in release notes, suppressed kmp package : zypper rm drm-kmp-default. But freezes still appear at random times…

I’ve read this link before falling on this thead :
https://forums.opensuse.org/showthread.php/521519-Screen-Freeze-on-Leap-42-2-only-option-is-reboot/
It looks like the same problem on 42.2 and my computer (dell XPS 1210) is equiped with intel 945 GM !

I tried to follow the advice. First I tried to rename intel_drv.so so that “xorg manage in another way” but result is that screen start to blink at the end of the boot process and stuck there. Even failsafe mode leads to blinking screen. I had to boot on my old 13.2 to replace the intel_drv.so file in the initial way.

I tried also to force uxa acceleration but on leap 42.3, file /etc/X11/xorg.conf.d/20-intel.conf doesn’t exist… locate intel.conf returns nothing.

As the uxa seems to fix the bug on 42.2, is there a similar way on 42.3 to do the same fix ?

Thanks for any help,
Marc

that file does not exist you need to create it

kdesu kwrite /etc/X11/xorg.conf.d/20-intel.conf

and paste

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

in it then save and reboot
