https://bugs.freedesktop.org/show_bug.cgi?id=98146 --- Comment #13 from Darek Deoniziak --- I'm still using DRI2, but the worst thing is the issues I thought were solved are back. Tried updating drivers (using oibaf ppa all the time) and using single file with settings: Section "Device" Identifier "Graphics" Option "DRI" "3" EndSection How can I make sure that it is actually used? Also couldn't find configure script for intel to pass --enable-dri3. The output of cat /var/log/Xorg.0.log | grep DRI is: [ 4.875] (II) glamor: EGL version 1.4 (DRI2): [ 4.880] (II) RADEON(G0): [DRI2] Setup complete [ 4.880] (II) RADEON(G0): [DRI2] DRI driver: radeonsi [ 4.880] (II) RADEON(G0): [DRI2] VDPAU driver: radeonsi [ 4.881] (==) RADEON(G0): DRI3 enabled [ 5.034] (II) intel(0): [DRI2] Setup complete [ 5.034] (II) intel(0): [DRI2] DRI driver: i965 [ 5.034] (II) intel(0): [DRI2] VDPAU driver: va_gl [ 5.034] (II) intel(0): direct rendering: DRI2 enabled [ 5.055] (II) GLX: Initialized DRI2 GL provider for screen 0 Sorry for late comment, but I was trying to look around over the web to see if someone had similar issues. Seems like people don't have many problems with switching to DRI3. -- You are receiving this mail because: You are the assignee for the bug.
