--- Comment #22 from peterle@hottemptation.org 2011-03-30 06:56:43 PDT --- Scrolling is still painfully slow after a suspend-cycle with kernel 2.6.39-rc1. Working with tools like less is impossible :-(
Interesting: After a suspend-cycle normally not every virtual-terminal is affected, most times one or two vt still working fast. Here an example: 1. Boot 2. pm-suspend on vt2 3. resume from suspend 4. everyting still works fine! 5. pm-suspend on vt2 6. resume from suspend 7. scrolling is slow on vt1, vt3, vt4 but not on vt2
Sometimes pressing a button helps to speed up the scrolling. Not always, after a logout/login on a vt pressing a button while scrolling maybe doesn't work anymore.
