This has been a problem with both F15 and F16. After the laptop has gone into either suspend or hibernate mode, reviving it seems to work OK but then there are some strange issues:
1. The mouse movement controlled via the touchpad (alp?) has no acceleration anymore, making it very slow and sluggish; opening System Settings > Mouse & Touchpad there is no Touchpad tab anymore
2. The system hangs on shutdown or reboot. Normally, shutdown or reboot is no problem but after having been in either sleep mode or hibernation, the process just stops after all running processes have been stopped correctly and according to the log, all that is needed is the actual shutdown or reboot. All I can do is keep the ON/OFF switch pressed for 4 seconds to force shutdown.
I have tried switching from the nouveau driver to the proprietary Nvidia drivers but apart from the disaster that caused because of my second (external) screen preventing me from even login in (had to jump some hoops to get my out of that situation) that did not make any difference on the level of this sleep/hibernation issue
Tried all Dell related packages in the repository but still no changes...
Can anyone confirm these issues on similar or other machines? Or better yet, point me to a solution?
