From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8) Gecko/20051111 Firefox/1.5 Description of problem: I just updated to kernel-2.6.15-1.1830_FC4 and udev-071-0.FC4.2. After a reboot, everything was normal until start of X (login manager already broken, no errors while bootup, I don't use rhgb). The display in X was completely broken: I saw mainly grey horizontal bars but also some stuff on my desktop but in a resolution like say 200x100. I'm using a Thinkpad R40 with a Radeon Mobility 7500. I rebooted into kernel-2.6.14-1.1656_FC4 and the problem persisted, downgrading udev to udev-058-1.0.FC4.1 fixed the problem. In my Xorg.0.log I found: drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is -1, (Unknown error 999) drmOpenDevice: open result is -1, (Unknown error 999) drmOpenDevice: Open failed drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is -1, (Unknown error 999) drmOpenDevice: open result is -1, (Unknown error 999) drmOpenDevice: Open failed drmOpenByBusid: Searching for BusID pci:0000:01:00.0 drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is 9, (OK) drmOpenByBusid: drmOpenMinor returns 9 drmOpenByBusid: drmGetBusid reports pci:0000:01:00.0 which looks rather strange.

Symptom: Graphic login screen is grayscale and distorted/disjointed. Login is accepted but X-window corruption persists. Can be corrected by CTRL-ALT-BACKSPACE, after which the graphic login and user screens are normal. Observations: - Occurs with ATI Radeon 7000 graphic card and radeon driver. - Does not occur with nVidia GeForce 2 MX card and nv driver on otherwise identical system (ASUS A7V-133C, Athlon 1000/266, 512MB). - Does not occur if xorg.conf driver is changed from "radeon" to "vesa". - Occurs with kernel 2.6.14-1.1656_FC4 and 2.6.15-1.1830_FC4. - Occurs if inital run level is 3 and startx is invoked. - Does not occur if initial run level is 3 and gdm is invoked.
