Old post:

Hi again haven't been long since I last posted in this forum ;(
I've been trying to run qute litteraly any game on full screen but they refuse to work me,basically its just stack in the first frame and I either see my desktop background or a blackscreen with my WM left and top border, the only game that has worked untill now is 0ad (which if i remember correctly is windowed-fullscreen so not really the case to support...)
tried: alienarena, urbanterror, megaglest, 0ad

/etc/X11/xorg.conf
glxinfo_debug_verbose
/var/log/Xorg.0.log
emerge --info xorg-server/drivers xf86-video-intel and mesa
WM:dwm(either custom or gentoo official neither work)
CPU/GPU:Intel Pentium B960/Sandybridge

Not really in a hurry since I dont play that many games nowdays but still when I get back from work and I have some time to kill,id like to you now

things ive tried:
add resolution modes in xorg.conf
I removed gallium completely since "supposedly" my integrated gpu dosent support it(even tho it did on artix somehow)
tweeked some of the xorg.conf driver settings
cp'd /usr/share/something-something/drirc to /etc/drirc and ~/.drirc just in case(i now open source games but still thought i'd try)
enabled intel_agp on boot throught /etc/config.d/modules but lsmod says it is used by 0 other mods
prayed to a few religions including satanic ones
make bread to release my anger

The cause of most of the trouble was xcompmgr itself from my xprofile,picom works fine so if you are looking for a xcompmgr solution I haven't found one( one that works for me that is google "xcompmgr glx fullscreen games" will get you about 3 solutions there, if none work try starting x using startx using a normal user account

The only game that hasen't been resolved is alienarena,which still refuses to go fullscreen will post update if fixed
