I have problem with a VGA driver that is not detected on my Lenovo T420 with Ubuntu. 10.04

Output of lshw:

       *-display UNCLAIMED
         description: VGA compatible controller
         product: Intel Corporation
         vendor: Intel Corporation
         physical id: 2
         bus info: pci@0000:00:02.0
         version: 09
         width: 64 bits
         clock: 33MHz
         capabilities: bus_master cap_list
         configuration: latency=0
         resources: memory:f0000000-f03fffff memory:e0000000-efffffff(prefetchable) ioport:5000(size=64)

This is output from lspci -nn:

00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:0116] (rev 09)

When I install version 11 for testing it can detect the drivers:

00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09)

*-display

On Ubuntu 10.04, I tried to install the xserver-xorg-video-intel driver but I'm still unable to get the right resolution on my display.

I've already tried the suggestion on Display not detected on a Thinkpad T420, but still no luck.

sorry on 10.04 this is the output: *-display UNCLAIMED description: VGA compatible controller product: Intel Corporation vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: bus_master cap_list configuration: latency=0 resources: memory:f0000000-f03fffff memory:e0000000-efffffff(prefetchable) ioport:5000(size=64) –  user32065 Nov 3 '11 at 16:35
    
No need to comment it twice, just edit it in and add a single comment so I get notified. Perhaps the older kernel does not support your newer hardware, install the newer version (11.10) unless you really do not want to. –  Lekensteyn Nov 3 '11 at 16:42

with the following steps I succeeded to get the Lenovo T420 intel graphic running properly:

# apt-get install linux-image-generic-lts-backport-natty linux-headers-generic-lts-backport-natty

then just change the following line in your /etc/default/grub

 GRUB_CMDLINE_LINUX_DEFAULT="quite splash"

to

 GRUB_CMDLINE_LINUX_DEFAULT="quite splash i965.modeset=1"

don't forget

# update-grub

and of course a reboot!

you often can read something about 'i915...' but this seems to be for older intel graphics (compatibility issues?). I found (somewhere?) the device code for the intel HD 3000 which is i965.

What makes you think that your Intel card is not supported? Both lshw output shows that the Intel driver (i915) work:

configuration: driver=i915 latency=0

The output of lspci is missing the names because the data of the PCI devices is outdated. To update your local database of PCI device names, run:

sudo update-pciids

from my basic understanding, Intel VGA should create this file: /etc/X11/xorg.conf, i try to locate it on my system it's not there. –  user32065 Nov 3 '11 at 18:18
    
@user32065 /etc/X11/xorg.conf does not have to exist, settings are automatically detected. –  Lekensteyn Nov 3 '11 at 18:35
    
what i did i upgrade to kernel 2.6-35.30, it's booting and last screen before login i got black screen. i reboot and enter grup mode, i issue the lshw -C to check the driver and it's exist this time, the problem now i'm getting black screen and if i revert back to old kernel 32-34 i will not get the driver installed. any help please. –  user32065 Nov 3 '11 at 19:12
