Bugzilla – Bug 199924
SaX2 ignores selected screen resolution for "Dell I815" on-board graphics and HP p720 monitor (vertical size is always 600)

(See also bug 129921 which was believed to be fixed, but actually is not) When selecting a graphics resolution of 1024x768 in SaX2, the test screen (which actually lacks display of actual resolution) looked OK, so I save dsettings for the Dell GX 150 with an I815 graphics. However fonts looked very strange when being logged on, and all windows appeared very high. So eventually I found out that the vertical size is just 600 pixel, not 768. This also happens to other (higher) selected sizes. Viewing the X server's log, I found that DDC failed to detect my monitor, a "HP p720", probably because of a KVM (Keyboard/Video/Mouse) switch. So I tried to select the monitor manually , but I found out that only on HP monitor at all is known. That bug had been reported some time ago, and it was expected to be fixed. I'm running the current online update version of SaX2. My graphics chip had vendor=0x8086 (intel), device=0x1132 (I815), subvendor=0x1028 (Dell), subdevice=0x00be, revision=0x02. The Xorg server uses driver "i810_smbus". Maybe this message during boot is related as well: Patching video bios 855resolution version 0.4, by Alain Poirier Chipset: Unknown (id=0x11308086) Unknown VBIOS structure failed [More info on request (if needed)]
Created attachment 96392 [details] Windows installation file "p720.inf" (from "mdf592en.exe") Inf file suggests that monitor is DPMS capable, that an ICM profile is available, that the max resolution is 1600x1200, and the frequencies seem to be 30-85,50-160. Hope that helps.
The intel driver depends on the BIOS and unfortunately it wasn't possible to patch the BIOS in a way that the i810 driver knows about the 1024x768 resolution. I'm sorry but this is a problem with the BIOS. Intel is currently rewriting the driver so it no longer depends on the BIOS
mass reopening all SuSE Linux bugs that are set to REMIND+LATER to change the resolution to WONTFIX (adapting to new policy)
not an issue with the new intel driver anymore
