An update to this report which might help with the solution: While the old system based on Kernel package version 2.6.32-3 worked, I've experienced graphics slowdowns after resume. Just today I've come across #587722 which seems to be related. It hints at installing firmware-linux. Its dependency linux-firmware-free was already installed, but firmware-linux-nonfree was not yet present.
When I installed it, I've experienced the same issue as Pietro, the submitter of #587722, namely that Kernel 2.6.32-3 doesn't resume at all anymore. However, with the newer kernel packages and in particular 2.6.35-trunk the resume works flawlessly now after several tries, and on top of it it also fixes the slowdown issue after resume. Therefore, in summary, Kernel 2.6.35 + firmware-linux-nonfree is the best combination for my system. Now I guess the next step is to find out if the non- free part is really needed. If my observations are correct, it might make sense to retitle the report accordingly. I will also add a note to #587722. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
