I've decided to test 64bits system, after some years beeing afraid by them, due to a bad experience xD Thus, on my Toshiba portege A600 (Intel Core 2 Duo U9300) I've installed Win 7 Pro 64bits, and just after Lucid 64bits. And I'm facing the same errors (see below). All was OK at the installation and on first boot. (Win 7 was even correctly recognized ;-) ) Then I installed the French language package, and all goes wrong. Not only I had the "raw edid error", but also Ubuntu refused to start. In recovery mode, I desinstalled the french language package (apt-get remove language-pack-fr), reboot, and all was ok again. Yeah, seems pretty strange... but really, I tried a lot of things, and gdm had never accepted to start. At last, I've rebooted in recovery mode, and the ONLY things I've done is "apt-get remove language-pack-fr" and "reboot", and I didn't had anymore the raw edid errors, and Ubuntu worked fine again. Then I installed the new kernel (2.6.32-21 -> 2.6.32-23), and again, I have the errors below. Nevertheless, I can start Ubuntu this time, even if it seems quite slow. I'll try the kernel above, and give a feedback. [ 16.034972] [drm:edid_is_valid] *ERROR* Raw EDID: [ 16.035021] <3>00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
