Hi, I am running Mandrake 9.0 distro and the X server 4.2.1 which came with it. The problem is that, after using X for some time, my system locks up completely. I mean no key combination works. No not even the Magic Sysrq. The only option is a hard reset. The symptoms: 1. Mouse pointer disappears. 2. No common action ( that means, I can't recreate it intentionally. ) 3. Occurs irrespective of GUI. KDE, Gnome all the same. 4. Complete system freeze. 5. May occur within minutes after the boot or after hours. What I have done: 1. Executed memtest yesterday and quit it in the 4th round since it did not show any errors. 2. Downloaded and installed the latest drivers/modules for my card (sis_drv.o and sis_dri.so ) 3. Tried increasing the graphics shared memory in bios. 4. Searched for IRQ conflicts but could not find any. 5. Disabled v4l in Xfreeconfig file. 6. Tried disabling glx too. but no change. The setup: 1. AMD Duron 800 Mhz. 2. 128 MB SDRAM. 3. K7SEM MoBo. Onboard audio and 3D acceleration. SiS730S chipset. 4. External conventional modem. 5. LG studioworks 56i 15 inch monitor. 6. 20 GB western digital HDD. 7. CD ROM and floppy drives. When the system is working it works like anything. I mean no cokplains as long as it is up. Audio is fine. mouse movements and all. everything is perfect. But only till the system comes to a complete halt. :(. Please guide me. Its getting on my nerves. By the way, the resolution is 1024x768 @ 16 bpp. Thanks a lot.
