492392 but this lists older kernel as fixed. 510004 but display does not look like it is in console mode. For display see photograph http://ubuntuone.com/p/3S1/ of the display after resuming and after submitting of the password. Before submitting the password the vertical lines were visible for too short a time to take a picture (timing problem). 574848 but only occasionally the screen is totally blank. I did also test the live cd of lucid and it resumed with blank screen from suspend. No horizontal lines. Steps to reproduce 1. Start computer 2. After booting to desktop select from top right menu suspend 3. After suspending press power button 4. Screen shows only occasional gray horizontal lines with max height of aproximatelly 1 in. 5. Input password -> vertical lines will be drawn for a longer time, can fill the screen up to 2/3rd:s of the height. Also the lines will have more colors than gray. It should be noted that 9.10 had similar occasional issue. With 9.10 the screen occasionally got garbled when switching user or after pressing ctrl+alt+f(n). But with 9.10 suspend worked and the display normally would revert back to normal after pressing ctrl+alt+f(n) a few times with different (n)'s. Also the behaviour was notably different as can be seen from photograph http://ubuntuone.com/p/3SJ/ Also it should be noted that with lucid ctrl+alt+f(n) trick does not work and altGr + sysrq + k does not have any effect. Also it should be noted that workaround of adding kernel command line option radeon.new_pll=0 as mentioned in bug 543045 does not have any effect.
