[SOLVED] Xvesa and low res monitors

[LazyLarry]

I seem to have an opposite problem to most. I have a 640X480 touchscreen LCD that cant handle the gui. ie when the system boots up, i get the normal text stuff on startup, but after startx, the display switches to the expected desktop, but its like the monitor can't sync and it just flashes repeatedly. I can just make out the core logo mid screen. If I plug in another monitor, ie normal dell 15" it does display the 640X480 signal correctly.
when the display flashes, i can do ctl alt del and get back to a prompt. playing with all options in xsetup and doing startx doesn't sort it.
I'm using tinycore plus 5.02 and the motherboard has a geode display chip

This board and display work fine with ubuntu.

Any suggestions?

Things work with ubuntu and Xvesa or ubuntu and Xorg?

[LazyLarry]

ubuntu and Xorg (i think). How do i check?

[Juanito]

"which Xvesa" and "which Xorg"

[LazyLarry]

which Xorg gives /usr/bin/Xorg, so i reckon thats the one.

[Juanito]

..so I'd try Xorg in tc, rather than Xvesa, and see what happens

[LazyLarry]

ok, so finally got Xorg running, but its the same flashing screen. I've modified the xorg.conf.vesa, saved it as xorg.conf to attempt to force it into low res, but no joy. I've added the Modes lines below

Section "Screen"
   Identifier "Screen0"
   Device     "Card0"
   Monitor    "Monitor0"
   DefaultDepth 24

   SubSection "Display"
      Viewport   0 0
      Depth     16
      Modes     "640x480"
   EndSubSection
   SubSection "Display"
      Viewport   0 0
      Depth     24
      Modes     "640x480"
   EndSubSection
EndSection

Also, I note the following section
Section "Device"
   Identifier  "Card0"
   Driver      "vesa"
EndSection

Should I change this from vesa? if so, to what?

Thanks for your help.

You probably need the geode video driver instead of vesa. It's not yet available for 5.x, so you'd need to compile it.

[LazyLarry]

ok, thanks for that. This is a bit "above my pay grade". Is there a guide i can follow to do this?

[LazyLarry]

or how about the xf86-video-geode driver? would that do the trick?

[curaga]

That's the one I meant.

[LazyLarry]

So, do I just download the xf86-video-geode.tcz extension, and modify xorg.conf like so?

Section "Device"
   Identifier  "Card0"
   Driver      "vesa" <-- change this to "geode"
EndSection

You should not need an xorg.conf file.

Hi LazyLarry

So, do I just download the xf86-video-geode.tcz extension ...

According to curaga you have to compile a new one, so using the one from the 4.x repository probably won't work.

xf86-video-geode recompiled for tc-5.x/Xorg-7.7 and posted
