Sony Vaio VGN-TZ195N Debian\Lenny 2.6.24 Kernel Suspend/ Resume Backlight Issues
 
Laptop: Sony Vaio VGN-TZ195N
Dist: Debian\Lenny
Kernel: 2.6.24

Suspend works fine, however when I resume the backlight does not work. I can see a faint image on the screen, and with enough external light I am able to launch a console window and type xset dpms force on, with no luck any suggestions?

temporary fix
 
echo 7 > /sys/class/backlight/sony/brightness
Console terminal (ALT + F7) and type the above.

I can confirm this is a problem with my VAIO VGN-N220E runing Slackware 12.1 .

Ubuntu 8.04 No Problems
Mandriva Spring No Problems



Word to the wise Slack / Debian are not laptop friendly.
