I applied the commit you mentioned on top of libdrm (2.4.40-1~deb7u2) sid; urgency=low and rebuilt the package. Unfortunately I think there is no difference. The glyph corruption is still gone but it is also still slow, so swrast still might be used. How can I check, what is used, without `glxinfo` installed? I could not spot anything useful in `/var/log/Xorg.0.log`. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/745608 Title: [915GM] font corruption on Intel GMA900 To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/745608/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
