Last modified: 2008-04-09 10:39:27 EDT
Description of problem: Display is incredibly slow, small errors abound. Probably related to incorrect display size? Version-Release number of selected component (if applicable): f8.92 How reproducible: 100% Steps to Reproduce: 1. Boot laptop, Advent 9115 2. Use NOAPIC ACPI=off to make above work 3. Thats it Actual results: Screen corrupted in small areas. Really extremely slow Expected results: Working fine. As in F8. Additional info: F9 selects (WW) VESA(0): Unable to estimate virtual size (--) VESA(0): Virtual size is 1280x768 (pitch 1280) While Kanotix found: (II) VESA(0): Not using built-in mode "1280x768" (width too large for virtual size) (--) VESA(0): Virtual size is 1024x768 (pitch 1024)
Created attachment 299245 [details] Xorg.0.log from f9 beta
Created attachment 299246 [details] Xorg.0.log from fedora 8 This uses 1280 x 768, showing that the 1280 is not a problem. F8 graphics works fine.
Test with liveCD from Rawhidr 20080327 showed a screen roateted by about 200 pixels right, but still slow and corrupt. Not really an improvment!
I'm impressed it works at all. Looks like sis BIOSes are extremely unhappy with how we're doing VBE now.
Um. is that supposed to be discourging? Or does it mean someone is looking at it? Its not good news with F9 supposed to be weeks away...
It means I was looking at it. And I even found a fix! How cool is that. Should be fixed in xorg-x11-server 1.4.99.901-19.
