Hello
I run Arch Linux, with it's latest x.org and kernel, and I have
compiled libdrm and the intel driver from git, and I update it today.
Buit this is issue exists even with the releases.
WIth UXA, rendering of the windows in my XFCE4-desktop goes just
fines, good performance, windows (exspecially GTK+) doesn't hang after
if I drag them over the screen, but there is lot of small tearing.
And I want this to go away, I do not use any kind of composition, and
I am using XFCEs window manager.
Here is my xorg.conf
Section "ServerFlags"
Option "AutoAddDevices" "Off"
EndSection
Section "InputDevice"
Identifier "Keyboard0"
Driver "keyboard"
Option "XkbLayout" "no"
EndSection
Section "Device"
Identifier "Card0"
Driver "intel"
Option "AccelMethod" "UXA"
Option "TearFree" "true"
Option "MigrationHeuristic" "greedy"
Option "TripleBuffer" "true"
EndSection
With SNA, the performance of the applications is muc much worse. If I
just replace UXA with SNA.
Thanks in advance for any help.
Regards,
Roberth Sjonøy

AFAIK you'd just be getting lucky with SNA, as opposed to UXA. However, for the SNA slowness, you should file a bug and include the following information: lspci -n -s 2.0 /var/log/Xorg.0.log dmesg with drm.debug=0xe sometime after experiencing the slowness <feel free to mention UXA is much faster> -- Ben Widawsky, Intel Open Source Technology Center _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx ^ permalink raw reply [flat|nested] 12+ messages in thread

Your option is SNA + TearFree, or use a real composited desktop. I know it sucks.
