rmcd, if you used the default Radeon drivers (i.e. removed fglrx) would this provide a WORKAROUND?
** Tags added: latest-bios-9skt81aus ** Description changed: - This new report is identical to 1337373. I thought this bug was fixed, - but it is not. From the previous bug report: - - This appears to be the same bug others have reported --- lock screen is - used, the display goes blank, and then the display remains black after a - key or the mouse is touched. + When lock screen is used, the display goes blank, and then the display + remains black after a key or the mouse is touched. For me, this only occurs after the display has been blanked for a period of some hours (typically overnight).
