Dear all, We finally found a workaround : the grub option "pci=noacpi" allows to boot using intel driver ! I however have no idea to explain why it works...
Here is the link that helped us : http://markmail.org/message/msojtkj4o4klho3t?q=lkml+list:org.kernel.vger.linux-kernel The problem seems to be closely linked not only to the graphics chipset, but also to this particular Foxconn mother board with an intel atom processor. I hope it helps. ** Description changed: + (see post #12 for a temporary solution) + Hi, When booting on a Natty live-USB on my computer, a gnome-panel like desktop is loaded instead of Unity. It seems to be related to a problem with the intel graphics driver : the Xorg.0.log tells "(EE)open /dev/fb0 No such file or directory" and then the vesa driver is used instead. If I create a xorg.conf file (by default there's nothing), with ' Driver "intel" ' in ' Section "Device" ', then restart X with "sudo service gdm restart", Xorg fails to load (No devices detected, Fatal server error:No screens found) and I see a command-line prompt (same result as when trying Ubuntu 10.10). If I do the same but with the line ' Driver "vesa" ', of course it works the same as without xorg.conf. Except that Xorg.0.log shows no error at all. Nevertheless, Ubuntu 10.04 works, with compiz effects activated ! The intel driver is OK in Xorg.0.log . Note that at first with 10.04 I had freezes, but they were corrected by installing compiz-fusion-icon, selecting the "indirect rendering" option, and making this change permanent. I can't say more. I'm not sure what package causes the problem. Sorry also for my bad english. Graphics card : Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) I tried every option available when booting on the live-usb (nomodeset for instance). I also tried using another screen, which works with Ubuntu 11.04 on another computer. Same problem. xserver-xorg-video-intel: Installed : 2:2.14.0-4ubuntu7 xorg: Installed : 1:7.6+4ubuntu3 I hope it will help, thanks for your attention !
