Hello!

I have an old laptop with a Savage videocard in it.. (S3 graphics vt8375 [pro savage8 KM266/KL266])

I made a fresh stage 3 install, and added framebuffer + savage driver in the kernel. Emerged x-server, when i hit startx i get a very screwed up screen, the screen is all black, and then you can see the first command lines in two xterm windows, and also the mouse.

When i stop the x server, i get many strange pixels even in the console.

The framebuffer console do work though..


Any ideas?

X and framebuffer do not work very well together any more.

If you don't need the framebuffer, use VGA text console instead. If you need the framebuffer, consider using xf86-video-fbdev instead of the savage driver.

Hello!

Thank you very much for your help.

I did de-activate fb in the kernel and i see progress in X. But i have this strange problem with the mouse now,
The coordinates seem to be off, and the mouse cannot move all over the screen, its like the mouse have a smaller window? Any ideas on that? Never seen this before haha :)

You can try to disable the hardware cursor in xorg.conf
/etc/X11/xorg.conf.d/10-device.conf:
Section "Device"
    Identifier "savage"
    Option "HWCursor" "off"
EndSection

Thanks again!

That sure did work.

But there is something still fishy, the fonts are a bitt rough, and moveing an xterm window around is _extremely_ slow. Dont know whats up with that?

Non-smooth fonts can be due to scaled bitmap fonts or lack of hinting in outline fonts.

Bitmap fonts should be uninstalled unless there is a reason why you need them (x11-base/xorg-x11 metapackage pulls them in by default). And if you need them for legacy X applications, disable their use in fontconfig applications via "eselect fontconfig". Make sure that you have proper outline replacements (e.g. media-fonts/dejavu or virtual/ttf-fonts) installed.

The slowness is because XAA support was dropped from the X server and EXA is does not work correctly in all cases. You can try to switch to EXA acceleration:
Code:
Option "AccelMethod" "EXA"

Hello!

I tried to add that options to the same section as the device from your earlier post.. But no change..

I will have to read up on the font problem, because that is completely new to me :)
