 |
|
Hello,
I'm having an issue with modesetting driver with one of my laptop.
From time to time, the refresh rate of the display drops so badly that the only way to recover is to reboot it (kill & start X is not enough) or else the system is totally unusable (minimizing / maximizing windows can take more than 2 seconds..)
It seems to be triggered when opening some video files in fullscreen or when playing games most of the time.
In the xfce display menu, the "refresh rate" dropdown menu shows the following :
| Code: | 60,02 Hz
119,97 Hz
119,94 Hz
59,81 Hz
59,91 Hz
50,05 Hz |
Now if I instead use xf86-video-intel (instead of modesetting) with the following conf :
| Code: | Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "sna"
Option "DRI" "crocus"
Option "Tearfree" "true"
EndSection |
then the xfce display menu only shows the following refresh rate :
and I can't reproduce the issue.. All works fine.
Unfortunately I can't remember when the modesetting issue happened the first time, a few months ago I would say.
The modesetting driver worked just fine before that so I don't know what's going on.
Xorg.log doesn't show any error or suspicious messages when the refresh rate drops, same for dmesg... I have not a single clue except the funny refresh rate values (119 Hz..) with modesetting driver.
Any idea ?
