Video card is Matrox Millenium G550 Monitor is Samsung SyncMaster 213T System is Linux Fedora Core 4, 64-bit version With X started the screen becomes garbled. Text is difficult to read, at times unreadable, effectably it is unuseable. This means that updates cannot be applied. The problem showed up when creating the system. It had to be done using text mode installation, because text mode is OK. On FC3 there are no problems.

If that doesn't resolve things for you, please re-open.

I see a garbled screen and I can recognise the icons and images and some of the text. I have tried to swap libvgahw.a as suggested by Mike Harris with the same module from FC3 to no avail.

Yeah, i've been pretty hasty with a conclusion there. I'm blaming cafeine :p What did digging for mga problems turn up? Have you tried X.org CVS or a recent snapshot?

I didn't find anything similar to my problem when searching for mga. I haven't tried X.org CVS or recent snapshots. I am relatively new to this and since I cannot run FC4 I don't know how to add changes to it. Please advice.
I have made another try with the monitor connected to the DVI port and here the symptom is different. Here it hangs with a black screen.
There is a chance that this still is a gcc4 issue, a problem similar to what is occuring in vgahw. If replacing vgahw with a gcc 3 compiled version is possible, then maybe a gcc3 compiled mga driver might be a good way forward for testing. Grab the FC3 X (is this 6.8.2 too?) and take out the mga driver, move the fc4 driver out of the way, and run the fc3 one.

I'll test it, but since I am leaving early today it may not be before Monday. xorg for FC3 is 6.8.1
OK. Ran the FC3 mga driver. Suppose it was mga_drv.o. It didn't help a bit, in fact X wouldn't load so it switched to text mode. Second thing I tried was taken out of bug #161242. Some have there reported problems similar to mine and a new set of modules were compiled for xorg with a fixed gcc. From that I picked libvgahw.a and mga_drv.o and copied them to my FC4 system. But that didn't help either. Would you like to see a photo of it?
This is the pci config space access problem. https://bugs.freedesktop.org/show_bug.cgi?id=2880 https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=163331 Fixed in fedora rawhide: 6.8.2-45

I suppose 6.8.2-45 refers to Xorg, but where do I find this "rawhide"?
Sorry, it use to be called "rawhide" but it is now called "development". http://download.fedora.redhat.com/pub/fedora/linux/core/development/ (You can also ftp to the same adress) You will also need to update glibc.

Thanks. How many of the xorg-x11 and glibc rpms should I install?

How many of the xorg-x11 and glibc rpms should I install? If you're using FC4 you should be able to use yum to upgrade the required RPMs: yum --enablerepo=development update xorg-x11 We also do plan to release an FC4 update with this fix shortly, though.
