Created attachment 46658 [details] X server log exhibiting crash Steve M. Robbins <steve@sumost.ca> noticed that uninstalling the ati driver on his system caused X to crash at startup. It turned out to be a misconfiguration --- since the right driver to use (radeon) was not autodetected, X used the fbdev driver. The fbdev driver is not supposed to make Xorg crash, though, hence this report. The good news: > I can confirm that *without* xserver-xorg-video-ati installed: > > 1. If I comment out the virtual directive, there is no crash. > 2. If I remove xorg.conf completely, there is no crash. > > There is still a bunch of diagnostics in the log file: > > [255110.061] (==) Depth 24 pixmap format is 32 bpp > [255110.264] (==) FBDEV(0): Backing store disabled > [255110.264] (EE) FBDEV(0): FBIOPUTCMAP: Invalid argument > [255110.264] (EE) FBDEV(0): FBIOPUTCMAP: Invalid argument > [255110.264] (EE) FBDEV(0): FBIOPUTCMAP: Invalid argument > > Once I install xserver-xorg-video-ati, I can remove xorg.conf and it > runs using the RADEON driver.
