Problem manifested itself after upgrading 8.0 -> 9. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Log into gdm 2. Work. Fetch coffee. 3. Log into gdm again, praise the extinction of any unsaved work from Step 2.

Can you attach your modules.conf, /var/log/messages, X config file also please? TIA
Will do tomorrow after reproducing the problem. Just for the records: system works flawlessly since yesterday with a PCI-based ATI board (no other changes).
Same error with a Gateway Solo 5350 with 830 chipset.
Same error on HP OmniBook XE3 GF with i830 chipset
After reconfiguring X there is an another error: There is not enough RAM to start X in 1024x768. This laptop worked before with RedHal Linux 7.3 and Intel driver at http://support.intel.com/support/graphics/linux/graphics.htm I tried to compile this driver but it fails on RedHat Linux 9.

I reconfigured X again setting manually the memory size. gdm started well. I had to set dri support manually, but it worked wery well later for the next reboot. After reboot I got the following: Error in I830WaitLpRing(), now is 3660, start is 1659 pgetbl_ctl: 0x1ff60001 pgetbl_err: 0x0 ipeir: 0 iphdr: 7d8e0001 LP ring tail: 0 head: 10 len: 1f001 start 7fde000 eir: 0 esr: 0 emr: ffff instdone: ffc1 instpm: 0 memmode: 108 instps: 824 hwstam: ffff ier: 0 imr: ffff iir: 0 space: 8 wanted 504 The full log file will be attached.

The problem is solved on my machine. I updated my system to the latest errata packages, and reconfigured X again. It didn't start. I added line Load "dri" to Section "Module" and X started well. I attach my current XF86Config.

sp@osb.hu) You're using what appears to be a custom kernel and custom built XFree86. If my assumption is correct, there's no proof this problem is fixed yet in Red Hat officially released binary RPM packages. This is a kernel bug IMHO, and requires kernel fixes. If the newest kernel does in fact fix this problem, I wasn't aware. I'm reassigning this to the kernel component for comment, etc.
Correction... you appear to be using only custom built input modules (synaptics). I still need multiple confirmation the issue is fixed if it is indeed fixed.
I use stantard (or standard errata) components: $ rpm -q kernel kernel-2.4.20-20.9 $ rpm -q XFree86 XFree86-4.3.0-2 I use synaptics input module, but it worked before with standard mouse module with ps2 protocol. I may kernel (i830) problem, but I think X configuration program may put Load "dri" line to XF86Config.
I just received this error for the first time.
