Created attachment 108236 [details] Xorg log I'm on Archlinux on a HP 840 G1, when I launch emacs in graphic mode (or conky) with Xorg 1.16, the X server segfault and I return to tty. Firefox, Thunderbird etc.. works however. If I switch to xorg 1.15 (with [xorg115] repo), the bug doesn't appear. If I uninstall xf86-video-ati, the bug doesn't appear too. I don't know if the problem is xorg-server or ati-radeon, so I put the bug in radeon driver section.

You'll have to attach gdb in order to grab a sane backtrace (if at all possible).
(In reply to Chris Wilson from comment #1) > You'll have to attach gdb in order to grab a sane backtrace (if at all > possible). Do I have to recompile Xorg ? (as seen on https://wiki.archlinux.org/index.php/Debug_-_Getting_Traces) because it will just give me no debugging symbols found. I'll send the backtrace in a few minutes.
Created attachment 108245 [details] GDB Backtrace I don't really know if it s how to do a backtrace, because I didn't recompile Xorg.
Created attachment 108246 [details] GDB Backtrace 2 just after launching emacs I made a backtrace just after launching emacs and before X closed.

You need debugging symbols for xf86-video-intel at least, having for Xorg as well would be helpful.
Thanks for your help ! I'm gonna try to recompilate xf86-video-intel and xorg-server with debug flags with https://wiki.archlinux.org/index.php/Debug_-_Getting_Traces (it's well the right thing to do ?) Sicne you moved the bug to intel driver, I tried xf86-video-intel-git (from AUR) and I realized that the bug didn't appear anymore but if I try to use PRIME with xrandr --setprovideroffloadsink radeon Intel (the radeon card was well shown in xrandr --listproviders) and with a DRI_PRIME=1 glxinfo | grep "OpenGL renderer" it only shows OpenGL renderer string: Mesa DRI Intel(R) Haswell Mobile when it should show the Gallium 0.4.
Hmm, could you attach the updated Xorg.0.log?

That looks right (given what little I know about Arch).

The last backtrace doesn't match the one in the Xorg.0.log.

Maybe try $ LIBGL_DRI3_DISABLE DRI_PRIME=1 glxinfo (or compile -intel with --disable-dri3)
The last Backtrace was for the non-git intel driver, I will make a Backtrace as soon as I have another computer to do it. PS : the non-git version of xf86-video-intel of Archlinux includes some patchs, I will attach a tree of my the directory I use to compile

Hi ! I'm sorry, I'm in programmation school and I had a lot of work these days ! I recompile the git version of xf86-video-intel with debug flags and now, I'm able to use the amd card ! ~|⇒ xrandr --listproviders Providers: number : 2 Provider 0: id: 0x7d cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 6 associated providers: 1 name:Intel Provider 1: id: 0x53 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 2 associated providers: 1 name:radeon ~|⇒ xrandr --setprovideroffloadsink radeon Intel ~|⇒ DRI_PRIME=1 glxinfo | grep "OpenGL renderer" OpenGL renderer string: Gallium 0.4 on AMD OLAND But now, when I launch steam I have strange glitches, every minutes, the steam window is a lot of hard colors for 1 seconds. And when I launch Borderlands 2, during the game it seems that every seconds, it shows me the current image, and every other second, it shows me a one second in the past image. And when I try to launch Super Meat Boy, it tells me that the library GL_ARB_buffer_object is missing, so, it's a strange problem. To sum up, I have - A git version that make me straaaange bugs. - A stable version that segfault when I use emacs, conky, sometimes with firefox when I deal with selection and scrolling. What do you want ? I can give you the backtrace (with the debug flag, I can deal with it easier now) or the log if you want ! Thanks :)

I'm confident that I know what bug you are hitting in the current release (and which is fixed in git). So the question is do you see the same OpenGL/PRIME bugs in the stable version? If not, can you attach the Xorg.0.log from the git compilation?
Created attachment 108532 [details] Xorg.0.log from the git compilation when the "glitch" bug appears ! The bug only appears from the git compilation.
Do you need a steam log of the moment there is the flitch bug ? You found the bug recently from the backtraces ? Thanks a lot for your help !!
Should I try the git version of the ati drivers too ? I tried the last version, but I still got the OpenGL bug :/
Or do you want me to open another bug report ? Thanks :)
This same bug has been tormenting me for a while now. I have a different hardware ([Radeon HD 7730M]). Does another trace help?
The segfault is fixed. Now it sounds like you just have the lack of sync issue between intel/radeon, bug 70055 (not quite, it's a slightly orthogonal problem but is related!)
(In reply to Chris Wilson from comment #23) > The segfault is fixed. Now it sounds like you just have the lack of sync > issue between intel/radeon, bug 70055 (not quite, it's a slightly orthogonal > problem but is related!) PRIME sync is now supported from ~v4.9 (a radeon fix may need v4.10, not sure if that made it into v4.9). That should be all parts to this bug fixed...
