I've done a clean install from from the KDE PClinuxOS 2011.06, and after a littlebit of tweaking the resolution is fine, the display works.
Re-installing is no problem, it's my spare machine, and no important data on it.
If I do a full update (synaptic) some 258 packages are installed, but after the reboot, there is no way to log in, I can't get to a working desktop.
After that I re-installed the same release again, and did a full update again, this time I unmarked the openchromedriver update, leaving the openchrome 0.2.904-4PCLOS2011, and not upgrading to openchrome-20110523-1pclos. After the reboot everything works fine.
So now I did do the upgrade of the driver, and after restart, after grub, I'm left with a login prompt, no gui, no KDE.
Before I receive a comment on why I did the update if everything works, I was just curiuos if it is realy this driver that is the cause of the problem, and yes, it is.
1: can I return to the previous version of the driver? and this from the CLI? how please?
2: If I need to re-install (no probs, I know how) can I lock out this particular update of this driver? Permanently?
3: will locking out this driver update cause problems in the future? I see a lot of updating going on with Xorg and KDE
I would like to mark this thread as solved, because I see that other forummembers have had issues with this Via chipset.
