https://bugzilla.kernel.org/show_bug.cgi?id=34082 Summary: Incorrect / missing device id in radeon_atombios.c Product: Drivers Version: 2.5 Kernel Version: 2.6.38+ Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri@kernel-bugs.osdl.org ReportedBy: zhamahn@gmail.com Regression: No I have an Acer TravelMate 5730, and the scenario described around line 434 in radeon_atombios.c applies to this model as well. The problem is that the 5730 has a different device id than 5730G (at least my machine has). Changing the relevant id from 0x95c4 to 0x9591 fixes everything for me. Without changing the id, HDMI output works only if I turn it off with xrandr and then use DVI (which this laptop doesn't have) and it doesn't even work that well then, I also get lots of invalid EDID spam in dmesg. ...

This patch fixes the problems mentioned above. It just copies the entry for 5730G and changes the device id. */
