Comment 126 for bug 30447

Problem still appearing since Dapper, Edgy doesn't resolve it (either fgrlx or ati). On logout, reboot, shutdown i get garbage on the screen, no switch to a tty, no kernel magic keys (Alt+sysrq+RSUIBO) However, in Dapper i felt my CRT monitor (a 15'', 1280x1024) was very quickly switching frequencies/resolutions several times on logout just before the lock (i use it in 1024, but the login screen maybe tries 1280 and/or different frequency).
So i forced it on 1024x768@60hertz only, lock completely disappeared (40+ reboots). HTH someone. Problem returned with edgy+fgrlx, one in 10+ reboots (what makes it very difficult to track down). Video overlay+opengl option doesn't resolve it, uncommenting dri makes the 3d acceleration go away.

[A troll follows :-)] I think this is an EXTREMELY serious problem, it's a deal breaker for ubuntu; linux people on forums, ircs, etc, should be concerned with such problems instead of trolling like what, anyway, linux doesn't need at all to be rebooted and such idiocies. (what about dual boot and the 200W on electricity bill).

So, i'm thinking on reverting on dapper, since edgy took away also my mic capture (on an onboard sound blaster live 24 bit). BTW, i can only boot edgy's live cd by quickly going to a console during the splash and reconfiguring x with vesa, since the option safe mode graphics locks also.

kubuntu edgy (dist-upgraded from dapper), ati x700. My other PC with a Radeon7000 works just fine (ati driver since incompatible with fgrlx).
