I'm dealing with the same problem although the computer is a Acert Travelmate 5530-704G32Mi (AMD RM-70, 4 Gb RAM, Ati Radeon HD 3470XT).
I have tried all drivers (radeonhd, fglrx and ati) but none seem to get the monitor going. The best results have been with fglrx - I can hear the sounds of gdm and gnome (login sound etc) but the screen stays blank. When I tried to switch to the vesa driver I got the error message "no screens found". //Matthias -- Radeon Mobility HD 3470 Installation Problem https://bugs.launchpad.net/bugs/254908 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
