On my HP Envy, which has both an Intel on-chip graphics card and an Nvidia Geforce:

*-display UNCLAIMED

   resources: irq:46 memory:d3000000-d33fffff memory:c0000000-cfffffff ioport:6000(size=64)

I have trouble with all newer kernels. I basically had to install 12.04 LTS and use their 3.5 kernel family to get the system to boot. The 3.8 from 12.10 or the newest 3.11 from Ubuntu 13.10 leave me with a black screen upon boot. On one occasion I did hear the "log in" sound, but the screen did not display anything. I have purged all nvidia drivers so I guess it should just use the intel drivers, but apparently this is all messed up with newer kernel versions.

This is different from the other "nvidia boots into blank screen" bug in that I don't rely solely on an nvidia card. Surely the intel on-chip card should be supported and leave me with something different from a blank screen?

Again, it only works with kernel versions 3.5.0-41-generic, not with the 3.11.0-12 one that ships with Ubuntu 13.10.

When I go into the grub menu and change the boot options from 'quiet splash' to 'nomodeset' I am able to boot the system, but then I don't get any graphics and trying 'sudo service lightdm start' doesn't succeed (I get 100% CPU for apport, but this doesn't do anything either, so I kill it).

Help, I'm all out of ideas.

EDIT: Let me add that I'm using the EFI boot system and have a dual-boot installation with Windows 8.

Turns out that everything was more or less fine, just that the screen brightness upon boot was set to 0. I have no idea why this change in behaviour coincides with going to a newer kernel, but at least now everything works when I just increase the screen brightness.

Next step: Figure out how to make it boot with full brightness.

I have exactly the same problem on the same PC and also figure it out that increasing screen brightness showed up login screen.

Did you manage to change screen brigthness != 0 at start up?

Concerning the graphics card, do you manage to change between intel/nvidia?

Thank you

  • I found that it is pretty random. Sometimes it starts up with normal brightness, sometimes it doesn't. There's a tip here http://askubuntu.com/questions/79983/screen-brightness-reset-to-minimum-after-every-reboot but it doesn't seem to work reliably – Lagerbaer Nov 02 '13 at 23:13

Uninstall all previous drivers you have and do the following:

sudo apt-get install nvidia-319 nvidia-settings-319 nvidia-prime

Then go to nvidia drivers setting page and set intel gpu for daily use.

PS: The prime package is for Hybrid systems, this will work perfect for you, if you find any updated driver please tell me and I will change the 319 for the newest version, thank you.
