Upgrade from Slackware 10.2 to 12.0

Posted 12-31-2007 at 06:47 PM by zzzy

Computer:
HP Pavilion ze4547wm (ze4500 series) laptop with Radeon IGP 340M video card.

Reason for update:
Frequent Firefox crashes with embedded flash content even though system was up to date with patches, and Adobe (ex Macromedia) Flash plugin was latest version. Decided this must be a lib conflict.

Procedure:
Followed the instructions on found in Slack12.0 DVD/upgrade.txt. Uneventful except I was not upgrading from Slack 11.0 as instructions assumed.

Trouble:
Xorg would not display a stable, usable image. Display breaks as though refresh or synchronization were wrong --pretty weird for an LCD panel.<!--break--> Booted off a SLAX 5 live CD (kernel v. 2.6.16), did xconf (this is a SLAX X11 autoconfigure util) and was able to use X/KDE; grabbed the Xorg.conf file and used as-is under Slack 12 to no avail.

Troubleshooting:
Tried all sorts of autoconfigs, manual configs, custom modelines, making sure I stick to 60 Hz VSync. After a couple of days of on-and-off struggle, I finally came across xf86-video-ati-6.6.3 in the the extras package repository. Googling for xf86-video-ati-6.6.3 yielded the comment below from the official Slackware -stable change log:

Some people are getting a black screen with newer driver versions, so here
is an alternate to try, just in case.
Additionally, at ftp.slackware.com/extra there is a README file that says:
Quote:
If the ATI driver in the main tree doesn't work, then
try this one. You may have better luck.
D'oh! Problem solved.
