problem with video card, monitor unknown

Asked by DavidSan on 2012-02-07

I everyone, I have no experience with Ubuntu. I have installed it a couple of days ago. I have noticed that some of the hardware appears as UNCLAIMED when I used the "lshw" command. In particular, the video cards (both intel and ATI Radeon from a dell vostro 3450). Of course I have got very low screen resolution and monitor appears as unknown. Any idea on how to intall the drivers and make them work?
Thanks a lot.

There is an 'additional drivers' app in dash, run it and enable the driver..

I have installed Ubuntu 10.04 LTS for 32-bits. I do not find that application, but I have tried with "hardward drivers" app. The only driver I have in the list after searching is the Broadcom STA wireless driver but it says "this driver is activated and currently in use" What should I try?

Thanks

Have you tried the Oneiric liveCD? The later driver and kernel may help

DavidSan (david-sango) said : #4

I will try. If it works should I install it from the CD? and format the partition where 10.04 LTS is installed?

Can you give the output of:

sudo lshw -C display; lsb_release -a; uname -a

Thanks

Oh jeez it's not a system with a switchable GPU is it, one for power saving and the other for gaming etc...

I am afraid it is. In windows I am prompted to choose between two alternate configurations for video performance (the first time I run an app)... I think the name of the app is catalyst control center of Radeon

That nonsense is only supported fully in Windows. Both Nvidia and ATi have expressed zero interest in supporting this in any thing else. There is bumblebee which may help but I am not sure you will get too far with this...

DavidSan (david-sango) said : #10

I have tried the 11.10 version (64-bits) and it apparently solves the problem (at least the video cards do not appear as "unclaimed") but the cpu overheats and the fan is always running. Which version would you keep the 10.04 LTS or the 11.10?

Can you help with this problem?
