Here are the steps I followed with the help of to fix the issue using daily build of Quantal on new generation Atom Netbook. If you look closely you can see the screen actually displays what it should, but the backlight is off. The black-screen problem is in fact a backlight brightness issue. Any ideas?īTW, this is a problem I'm helping a friend with, I don't have direct access to the machine.
Ideally, since I don't think I can trust the gma500_gfx driver or that from Meego (the one in Sarvatt's PPA), I would like to use the vesa driver (probably reverting to 12.04), and specify the resolution in a nf file, but I can't seem to get this to work. Additionally, adding nomodeset to the kernel command line does not help with either the resolution problem or the blank-screen problem.This seems to have no effect, with the resolution stuck at 800圆00. Where the modeline comes from DDC, as reported in /var/log/Xorg.0.log. This causes Ubuntu to boot into a 800圆00 resolution.Īfter this, I've tried using the following nf: Section "Device" On Quantal I've blacklisted the gma500_gfx driver to force the use of vesa.The video=1024圆00 option doesn't work here either. The installed system boots to a blank screen. The live image boots with the correct resolution. I've tried installing a daily build of Quantal.I've tried passing the kernel option video=1024圆00 with the above PPA, to no avail.Subsequent reboots lead to a blank screen immediately after grub. On first reboot, the screen resolution was correct. I've tried installing an older version of Ubuntu (10.04), since someone suggested there's an older driver that should provide basic support for the card, but the liveCD image wouldn't boot.That didn't seem to fix the resolution problem. I've tried installing a newer kernel (3.3+), since some people have reported success with it.I've looked around and tried several different solutions. This is a netbook that contains the infamous GMA3650 (aka PowerVR SGX5450) which is poorly supported by the Linux kernel. After installing Ubuntu 12.04 on a Toshiba NB510 the screen resolution is 800圆00 instead of the native 1024圆00.
