I just installed redhat7 on my AMD-K6 machine with a Matrox Millenium G200 with 8Mb SGRAM. I configured it using the RedHat7 installer and when pressing the test button for the X setup it worked fine. I choose to start the machine in runlevel 5 (X login). After rebooting after setup the X server crashed on startup when running the login manager. This resulted in init trying to respawn the X server continously causing my monitor to change frequency and resolution very very rapidly - I thought it might explode! It seems that the crash is related to DRI and/or the mga kernel module. I removed mga.o and now I can start X.
Uh forgot to add: The server complains about not having enough memory for DRI and then fails with signal 11.
Created attachment 5644 [details] X server startup log showing the crash happening
Installing the driver from Matrox (mga_drv.o) that can be found on ftp.matrox.com/pub/mga/archive/linux/2000/ solves the problem. The server no longer crashes when there isn't enough memory available to do DRI with this driver.
I am having similar problems with ATI rage card using drive r128. Also a AMD K-6 cpu. Configuration and test were sucessful. Upon reboot into runlevel 5 , the X server now restarts upon successfull login through login manager.
XFree86 DRI problems for both r128 based cards and mga cards should be fixed in the latest Rawhide version of XFree + dependancies. XFree86-4.0.2a-2 or later.
