[K8M800] Xubuntu does not display properly on Lucid alpha-1 with updates, on Averatec 3280

Running the 2.6.32-7-generic #10-Ubuntu SMP kernel instead, the symptoms are the same except that the screen is NOT offset . The tiny text window appears on the actual upper-left of the screen, with the rest of the screen filled with the normal Xfce blue screen background image.

Again, trying to switch to a tty with ctrl-alt-F1 through F6 results in a useless screen, with a multicolored background; switching back to the X display works with alt-F7.

Hi Peter.

Please use new mode switch by adding to your xorg.conf file following lines:
   Option "modeSwitch" "new"

Is it works for you?

Try also apply this patch.

Ensure that video playing is working.

Hi Bartosz -

The xorg.conf I'm using for both Ubuntu (Gnome) and Xubuntu has

Section "Device"
        Driver "openchrome"
        VendorName "VIA Tech"
        BoardName "openchrome"
        Identifier "Configured Video Device"
        Option "SWCursor" "true"
        Option "modeSwitch" "new"
        Option "PanelSize" "1024x768"
        #Option "PanelID" "0" #640x480, Single, Dithering
        # Option "EnableAGPDMA" "Off"
        # Option "NoAccel" "true"
EndSection

But I haven't made the patch yet.

Right now I have Ubuntu installed in my test partition; should I try
the patch also under Gnome?

Thanks, Peter

It's completely normal that you lose data on "Windows" platforms.
That's why you have a UNIX or Linux or BSD server for backups.

I tried building the driver with the patch on the Gnome version of
Ubuntu alpha-1, and the screen went blank after booting. I'm not home
to try logging in with ssh, but when I am, I'll try installing the
binary driver and continue on ... I won't have time to try xubuntu
until after the weekend.

Hello.
So the option:
Option "modeSwitch" "new"
nothing helps?

Is your computer have blank screen with this option?

Attach your /var/log/Xorg.0.log file.
If you can from after screen blank (or /var/log/Xorg.0.log.old after reboot).

Here are the Xorg.n.* log files from yesterday (I booted into Jaunty on the laptop and mounted the partition with /var/log/ on it to get these logs). And from xorg.conf, I have

Section "Device"
        Driver "openchrome"
        VendorName "VIA Tech"
        BoardName "openchrome"
        Identifier "Configured Video Device"
        Option "SWCursor" "true"
        Option "modeSwitch" "new"
        Option "PanelSize" "1024x768"
        #Option "PanelID" "0" #640x480, Single, Dithering
        # Option "EnableAGPDMA" "Off"
        # Option "NoAccel" "true"
EndSection

I do get a blank screen after booting into xubuntu with the patch in place.

Checking the patch in the driver sources, I have this diff file (difference between patched and old unpatched via_driver.c file):

# diff via_driver*.c
715d714
< pVia->UseLegacyModeSwitch = TRUE;
1592,1595c1591,1593
< if (pBIOSInfo->Panel->IsActive &&
< ((pVia->Chipset == VIA_K8M800) ||
< (pVia->Chipset == VIA_VM800))) {
< xf86DrvMsg(pScrn->scrnIndex, X_WARNING, "Panel on K8M800 and "
---
> if (pBIOSInfo->Panel->IsActive &&
> (pVia->Chipset == VIA_VM800)) {
> xf86DrvMsg(pScrn->scrnIndex, X_WARNING, "Panel on "

from lcpci, I have
01:00.0 VGA compatible controller: VIA Technologies, Inc. K8M800/K8N800/K8N800A [S3 UniChrome Pro] (rev 01)

Actually, the test above in #7 was done with ubuntu gnome, not xubuntu installed.

Also, I just rebuilt the driver with the patch removed (I was able to ssh in and do the rebuild of the driver), and ubuntu boots with the slit screen described in bug #495553, but it does run well otherwise.

After re-installing xubuntu and updating it, I can try the patch again, or possibly an updated patch. Possibly I'll wait until the alpha-2 ISO appears on this coming Thursday.

I have not tried Xubuntu since my last comment here. I'll try that
when alpha-3 comes out.
