startx fail: "screen(s) found, but none have a usable configuration"

Hi all smile

I've been stuck on this one all day - crawling through forum post, wikis and google! I still can't get it fixed, so I hope that someone could either point me in the right direction or give me a few hints...

I'm installing Arch as per the Beginner's Guide wiki. I'm using a pretty old machine. If I run lspci then the video card seems to be an S3 Unichrome Pro (CN400/PM800/PM880/PN800/PN880).

I got to running 'startx' and it failed, so I ran 'grep EE /var/log/Xorg.0.log' and this came out:

(EE) UNICHROME(0): No active output found.
(EE) UNICHROME(0): No outputs possible.
(EE) Screen(s) found, but none have a usable configuration

'startx' always ends up with 'Fatal server error: no screens found'.

I've tried the solutions posted up in older posts, with no joy so far. I'd be grateful for any advice!

Thanks!

I've stalled the xf86-video-unichrome driver, though I think xf86-video-vesa came along with the xorg install too.

Re: startx fail: "screen(s) found, but none have a usable configuration"

I have never used that graphics card myself, but this is what you get with

pacman -Ss s3
extra/savage-dri 7.9-1
    Mesa DRI drivers for S3 Sraphics/VIA Savage
extra/unichrome-dri 7.9-1
    Mesa DRI drivers for S3 Graphics/VIA Unichrome
extra/xf86-video-s3 0.6.3-3 (xorg-video-drivers)
    X.org S3 video driver
extra/xf86-video-s3virge 1.10.4-3 (xorg-video-drivers)
    X.org S3 Virge video driver

The Beginners' Guide also mentions

xf86-video-openchrome — VIA/S3G UniChrome, UniChrome Pro and Chrome9 video driver 

I can't help you directly but maybe you want to try one of these packages.

Thanks for your help. I've tried the Openchrome driver with no luck, I'll check out the S3 and S3virge drivers.

**Just gave them a spin, and no luck there either. I'll keep trying different drivers, if anyone has any other ideas for possible solutions, please let me know smile

X/video-driver don't always get the correct capabilities of your vdu - you may want a partial xorg.conf where you set modes manually ... and disable modeset in the kernel invocation line in grub.

Re: startx fail: "screen(s) found, but none have a usable configuration"

I have a laptop with an S3 UniChrome Pro adapter:
01:00.0 VGA compatible controller: VIA Technologies, Inc. CN700/P4M800 Pro/P4M80

It works for me with the OpenChrome adapter. I had to explicitly set the display size:

/etc/xorg.conf.d/15-openchrome.conf

Section "Device"
        Identifier "via-adapter"
        Driver "openchrome"
        Option "PanelSize" "1280x800"
EndSection

Section "Screen"
        Identifier "My laptop screen"
        Monitor "My laptop panel"
        Device "Configured video device"
        SubSection "Display"
                Virtual 1280 800
        EndSubSection
EndSection

Test with a basic window manager+xterm in your .xinitrc to make sure a desktop environment is not interfering with the pure xorg settings.
