Hi, I've updated from kernel kernel-2.6.13-1.1532_FC4 to kernel kernel-2.6.15-1.1831_FC4 with "up2date". Then I've restarted with the new kernel, but the Login-Screen is only visible for a few seconds, then the screen gets totally grey. With the "old" kernel kernel-2.6.13-1.1532_FC4 the problem still exist. I've removed the Packages kernel-devel-2.6.15-1.1831_FC4 and kernel-2.6.15-1.1831_FC4 with "rpm -e". The Package udev-071-0.FC4.2 was installed/updated as a dependency. It seems the problem is the module "radeonfb". This are the last lines of the file /var/log/messages after booting: Feb 19 10:22:59 warpy kernel: radeonfb: Found Intel x86 BIOS ROM Image Feb 19 10:22:59 warpy kernel: radeonfb: Retreived PLL infos from BIOS Feb 19 10:22:59 warpy kernel: radeonfb: Reference=27.00 MHz (RefDiv=12) Memory=200.00 Mhz, System=166.00 MHz Feb 19 10:22:59 warpy kernel: radeonfb: PLL min 20000 max 40000 Feb 19 10:23:05 warpy kernel: radeonfb: Monitor 1 type CRT found Feb 19 10:23:05 warpy kernel: radeonfb: EDID probed Feb 19 10:23:05 warpy kernel: radeonfb: Monitor 2 type no found Feb 19 10:23:05 warpy kernel: Display is GTF capable Feb 19 10:23:05 warpy kernel: Console: switching to colour frame buffer device 160x64 Feb 19 10:23:05 warpy kernel: radeonfb (0000:01:00.0): ATI Radeon Yd I've searched with "grep radeonfb /var/log/messages*" through all the message files. The String "radeonfb" never appears before I've done the kernel update. What has the kernel update changed? I have a ATI Radeon 9200 graphic card in my PC. I've tried to boot with the following Kernel Parameters: video=radeonfb:off video=vesafb" but without success. Booting into runlevel 3 is ok. But switching to runlevel 5 same problem. Any Help ist appreciated. Best regards, Detlef ___________________________________________________________ Telefonate ohne weitere Kosten vom PC zum PC: http://messenger.yahoo.de
