X version in 12.2?
Slackware 12.2 uses xorg-server 1.4.2. Up to date package revisions of Slackware 12.1 run xorg-server 1.4.2 as well.
To recap, I only substituted the xf86-video-intel-2.2.1 driver package from 12.1 in place of xf86-video-intel-2.4.3 found in Slackware 12.2
While the original intel video driver in 12.2 seemed to run xorg.conf. When KDE came up. I found myself unable to keep resolutions settings in KDE from taking hold and the kdm login screen seemed stuck in 1024x768 mode. Even more telling was getting apparent resolution changes after adjusting them in the KDE control panel and relogging back in to find resolution changes not taking hold. And finding the dpi settings and font sizes blown up in size. (Yes I hit that checkbox in KDE to save changes on login)
It was only after I changed to the older video driver (xf86-video-intel-2.2.1) from slackware 12.1 and rerunning xorgconfig that everything seemed to run correctly. The irony is the new xorg.conf in this instance is line for line the same as the original. Only the video driver is different.
