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.

Creating a USB boot disc for FGN-TZ195N
 
This is the most recent item I've found in this forum that deals with placing a modern linux distro on the Sony Vaio VGN-TZ195N laptop. This is a really nice (tiny but capable) laptop from 2007 that pokes along in running Windows "Pro" but would be nice for a linux distribution. So I am been trying to adapt Rufus to produce a 32GB bootable USB (also a Sony USB stick) for this Sony laptop using the latest Ubuntu release. This may not be doable and I may need to relax back to an earlier linux distribution or a different distribution.

Anybody having any luck with Linux booting from a USB on the Sony Vaio VGN-TZ195N laptop?

Thanks!
