Failure of xserver upon motherboard change


Hello everybody,

After 10 years of Windows, for the past two years, I have been using Linux with much satisfaction. One thing I find wanting in Linux is that it doesn't start the graphical server automatically (using a 'Standard VGA Adapter' as in Windows) after a change of motherboard with different graphics chipset. Only in Fedora, I found it automatically re-configured and started like Windows. In this regard, is there any package (in Debian) that needs to be installed to achieve this facility? If not, what should be done when the graphical server fails to start at motherboard change?

Thanks in advance for your help.
Allwyn

If it was working (starting) before you changed the motherboard - but does not start anymore now, you should at least see some error messages when the system is _trying_ to start the xserver.
Usually the xserver uses a configuration file ( /etc/X11/xorg.conf ) with parameters tuned for one specific graphics card - if you change the card but fail to adapt the configuration to reflect this change, it will likely no longer work.
Also: your system may be configured to use certain drivers (modules) to operate your chipset. If the new motherboard has a different chipset these drivers will (of course) not work - and X and probably other things will fail to work properly.
You will have to re-do your configuration - if you run a custom kernel you will likely need to make a new one with drivers for your new mobo.
HOW to do all this in Debian - I can't tell you - but you already did this - once upon a time...it will be the same now.

I believe the way to reconfigure the xserver was something like: dpkg-reconfigure xorg-server (just a guess)

Well, if you use one of the 'live CD' type distros (say knoppix), because they do complete hardware detection on every boot, they don't get fooled by a hardware change. Of course, this is one of the reasons that they boot more slowly...

If you were with SuSE, you'd be using SAX2 to reconfigure X, but on debian I'm afraid that I don't know.

Yep you got it.

Is this a onboard video card? If you stay with the same video card you may be fine. If not reboot into recovery mode and after you log in as root do the command posted.

Yes, mine is on-board VGA (VIA K8M800 and ATI RS482). If the motherboards have the same chipset, there is no problem. I did dpkg-reconfigure (at root) and now it is Ok. Thank you very much.
