Description of problem: On an Inspiron 9300 with the following chipset: (--) Chipset ATI Radeon Mobility M300 (M22) 5460 (PCIE) found X fails to start, leaving a black screen with no access to alternate consoles. Version-Release number of selected component (if applicable): I installed FC5 test 3 which contained the problem. I also upgraded to the rawhide of Feb 25, 2006. Test 2 also had the same problem How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: The X error log shows that it is failing to open /dev/dri/card0 Commenting out the dri module in xorg.conf results in a working X. system-config-display is overly kind and will re-add the dri module back in, which results in a non-working X again.
After ensuring you have updated to all the latest rpms in fedora devel, please attach your X server log and config file from the problematic invocation, as individual uncompressed file attachments using the link below. Also attach your /var/log/messages from boot time on to the problem occurance, and the output of: lspci -vvn rpm -qa |grep xorg |sort uname -a Thanks in advance.
Created attachment 125365 [details] Xorg.0.log when dri module is loaded
Created attachment 125366 [details] Xorg.0.log when dri module is commented out (X works, for comparison)
Created attachment 125367 [details] Current xorg.conf file (only diff between working and not working is the dri module commented out)
Created attachment 125368 [details] rpm -qa of the X files
Created attachment 125369 [details] /var/log/messages (no apparent errors here)
Created attachment 125370 [details] lspci output
Updated to latest Fedora devel (no X stuff or kernel changed) Attached X server log that failed and also an X server log with DRI removed. Attached the X config file. The only difference between the non-workging and working versions was commenting out the dri module to get a working X. Attached the /var/log/messages. It doesn't show anything unusual. I booted at runlevel 3, did a startx from root. Had to reboot via power button after X fails. Attached the lspci, and rpm output. uname -a gives: Linux localhost.localdomain 2.6.15-1.1977_FC5 #1 Thu Feb 23 14:53:53 EST 2006 i686 i686 i386 GNU/Linux This kernel version encounted the grubby scriptlet problem in the rpm file, so I edited in the grub boot paragraph by hand.
Ok, this appears to be a bug in the radeon kernel DRM module. We're going to remove r300+ support from the kernel module, as the userland driver is unstable and also not being shipped... *** This bug has been marked as a duplicate of 182196 ***
