** Description changed: - When installing 12.10 on our Thinkpad T22 laptops the display does not work. 12.04 works fine. + [Impact] + For xserver-xorg-video-savage: Display corruption in X on (at least) Thinkpad T22 laptops, making the system unusable. + For xorg-server: System lockup on boot. + + [Test Case] + Attempt to boot a system with one of the affected Savage cards; the Thinkpad T22 is at least one such system. + + The display will be corrupted beyond usability. + + Install xserver-xorg-video-savage and xserver-xorg-core from proposed, + and you should have a usable X session. + + [Regression Potential] + The X server patch touches only the DRI1 initialisation codepath; this is not used for the vast majority of systems, so breakage is low-impact. Breakage here would most likely manifest as an Xserver crash on startup. + + The savage patch switches the default acceleration method to EXA (from + XAA) and adds some fixes to EXA support. Since we don't build XAA + support into the X server any more, so switching away from it means + enabling acceleration, which can cause pretty much arbitrary problems, + but is unlikely to. In any case, problems would be restricted to users + of xserver-xorg-video-savage. + + [Original Report] + + When installing 12.10 on our Thinkpad T22 laptops the display does not work. 12.04 works fine. xserver-xorg-video-s3 is version 1:0.6.5-0ubuntu1 xserver-xorg-video-savage is version 1:2.3.6-0ubuntu1 I don't know if these are the packages involved but they are the ones that I suspect may be involved. This T22 model (and many other thinkpads from that era) use the "S3 Savage IX8" chipsets. Using the info from this link makes the display work. ===== http://www.physics.wustl.edu/~alford/thinkpad/T23_F17.html - Xorg :1 -configure + Xorg :1 -configure # ignore Configuration Failed message cp xorg.conf.new /etc/X11/xorg.conf - Edit the /etc/X11/xorg.conf file: uncomment Option "DisableTile" in the Section "Device" that contains the Savage driver options. + Edit the /etc/X11/xorg.conf file: uncomment Option "DisableTile" in the Section "Device" that contains the Savage driver options. ============
