Hi gnutemberg, I'm a longtime lurker as well and this is my second post :-) My first is related to this one. I just installed Debian 9 Stretch on my ancient T23 (love it) and it runs xfce at full 1024x768 resolution with its beautiful screen. For reviving this old laptop, Stretch is great. Ofcourse,...

After lots of time and effort spent trying to figure this issue out, I decided to wait till Debian 9 came out to try it.

My screen resolution is now fully 1024x768 with xfce on Debian 9 Stretch.

Enjoy
