Matrox G450 help
Last modified: 2005-10-31 17:00:50 EST
Hi I just purchased a Matrox G450 video card for my pc. And i first had the video card installed on windows and it works great. But that is a diffrent story when I go to linux. During the boot process i received a screen to remove the previous video card setting and setup the new video card. The software seemed to detect every thing but when I would go to test the settings the maching would lock up. So I rebooted to see if i did something wrong, but the same thing happened again. So then i placed the install cd's in and when the install program switched from text mode to graphic mode the video was distorted. I could see an image but not verry well, and during the middle of the red hat install it locks up. But when i place my old Millennium 2 pci video card it work like a champ. Wold you know of any reason for this to be happening? Please help in any way that you can. Jonathan Vice P.S. Here is a listing of computer hardware that i have: Tyan S1598 Trinity ATX motherboard AMD K6-3 400Mhz processor 256 MB PC100 memory Matrox Millennium G450 32MB-DDR (Matrox Millennium 2 4MB PCI / old) intel ether pro100 Zoom modem 56K ISA SB AWE64 value IBM 30 gig drive IDE Sony CD-RW 10x4x32 ATAPI Kenwood 42X trueX cdrom ATAPI Zip 100 ATAPI
What happens if you go to text mode without configuring the video card and run "Xconfigurator" (as root)?
With the g450 card text mode works great and I can login to any account. But it is when I setup the video card the the video card goes can't display a image when Xserver starts. The autoprobe detects the card, then i set the ammount of memory, color depth, resolution, monitor, and so on. It is when I test the seting the Xserver locks up the machine, and KDE doesn't start up.
I am having a very similar problem -- brand new Dell PC with Matrox G450 32MB DDR, etc. etc. Graphical install doesn't work at all -- get the initial Red Hat screen, distorted and wavy, then it locks up. I successfully installed everything using text mode until it got to the X server configuration. Then, while testing the resolution/refresh, it chooses one that is outside the parameters given (the Dell P1110 monitor just doesn't support 200KHz!) and doesn't time out. I finally hard-restarted it, and the exact same thing happens when trying to use Xconfigurator. The monitor specs shown (it correctly identifies the monitor) are correct, but it chooses a setting that is outside the allowable range, and then locks up. I have to telnet in and reboot (tried killing the X process, no dice) in order to get back in.
The Matrox G450 is not a supported video card. XFree86 4.0.1 contains drivers for the G400, G200, G100, but not the G450. You may or may not get the card to work with these other card's drivers. I do know that Matrox has been working on an XFree86 4.0.x driver in house though, so you may want to check their website out. Hopefully their work will get integrated into a future release of XFree86.
Yes, the G450 presents a genuine problem with Red Hat Linux 7. It is detected as a G400, and the symptom is the monitor uses a ridiculously high refresh rate, an d the system freezes. Should be better in future XFree86 releases.
