Hi all

I have a brand new HP dv6 (1240ez) with a fresh Ubuntu 9.04 installation.

I cannot set the display resolution to the correct value.

If I click on System > Administration > Hardware Drivers, I see no drivers.

On System > Preferences > Display I get unknown and can only set up to 1024*768 (4:3).

Any ideas how I can solve this resolution problem?

Thanks,
chloraldo

I tried with the LiveCD of version 8.10 too. Same problem as with 9.04.
No high resolution possible.

I would really appreciate some help here,
Thanks

Could you please post your hardware specs? (video card, CPU, etc)

Start by updating Ubuntu to the latest packages and then check if you have any new drivers.

Also, post the output of the command lscpi tiped in a terminal.

Suddenly the hardware driver appeared and now it works with the right resolution.

What still does not work is an external monitor. By the way, the laptop display is shown as "Unknown" in the display settings.

....:~$ lscpi
bash: lscpi: command not found

Do you mean lspci?
