Description Steve Ng 2001-03-20 15:52:04 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.76 [en] (Win98; U)

During installation and running XConfigurator properly detected SiS620 Video chipset and proper Monitor (HP D2835 UltraVGA 1280 17") 
frequencies. Selecting any resolution and bpp produces garbaged video. Redhat 7.0 does not have this issue. Cannot switch to XF86_SVGA 

Reproducible: Always
Steps to Reproduce:
1. Run XConfigurator
2. XConfigurator autodetects SiS620
3. XConfigurator autodetects HP D2835 UltraVGA 1280 17" Monitor frequencies via DDC
4. Select any resolution and bpp (eg 640x480x8bit) and continue
5. Video display is garbaged.

Expected Results:  A clean and proper video image.

My motherboard is PC-Chips MB748MR using SiS620 Chipset and 8MB of Shared-Video selected via BIOS. Tried changing the shared video 
memory to either 2 or 4MB does not help in any way. Intel Celeron 300A o/c 450, 128MB PC100 SDRAM, Initio INI-9200UW PCI Ultra-SCSI 
adapter, Quantum Altas II UW-SCSI 9GB HDDs, LinkSys LNE100TX PCI 10/100 Fast Ethernet Card
