Hi I just recently installed Ubuntu onto my laptop (Dell Inspiron 15r 5520 64-bit) alongside Windows 8. While Ubuntu 12.04.2 LTS seems to be working fine otherwise, in System Settings it is unable to detect my graphics card and shows as "unknown".
I tried the following commands and this is what i get:
$ lspci -v | grep -i vga 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) (prog-if 00 [VGA controller]) 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Thames [Radeon HD 7500M/7600M Series] (prog-if 00 [VGA controller])
I have the ATI one as far as I know, so what's with the Intel VGA being displayed??
Secondly, in System Settings > Additional Hardware I activated the ATI/AMD proprietary FGLRX graphics driver (post-release updates). The thing downloaded and installed itself and but it shows as "The Driver is activated but not currently in use". I don't really know what that means.
After some digging around, I tried the following commands as well but to no avail:
sudo apt-get purge fglrx* sudo apt-get install fglrx sudo aticonfig --initial
Next I went to the AMD site and downloaded the requisite driver from here I followed the steps in their instruction manual, used the following command again:
sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev*
and then went to the folder where I had download the driver and ran the installation file. I went through the setup process, did:
and rebooted my laptop. Still I am stuck at square one, however, my Hardware info now shows the ATI VGA driver in addition to an Intel one. Here are the names:
VGA compatible controller : Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) (prog-if 00 [VGA controller])
VGA compatible controller : Advanced Micro Devices, Inc. [AMD/ATI] Thames [Radeon HD 7500M/7600M Series] (prog-if 00 [VGA controller])
After I installed the downloaded ATI driver and checked System Settings > Additional Drivers, I see that the Raedon VGAs have been deactivated again, as shown:
Here is a link to the /var/log/Xorg.0.log. Hope all this info helps.
Please help me detect my graphics card, I need it for dozens of applications specially Compiz effects, games etc. I am a novice so kindly explain your answers as far as possible so that I can make the best of of them. Thanks in advance :)
