Hi all,

HP Pavilion dm4 with configuration as shown below

cpu intel Core i5 2.26 GHz
RAM 4.0 GB
Graphics processor 512MB ATI Mobility Radeon(TM) HD 5450 switchable graphics [HDMI, VGA].

I installed ubuntu 10.04 ( without AMD graphics driver) it was working fine, but when I installed AMD graphics drivers AMD Catalyst™ 12.8 Proprietary Linux x86 Display Driver, than the problem started from then When I boot I was get black screen.

Than I thought to upgrade from ubuntu 10.04 to 12.04 using the bootable pen drive but was getting black screen than read on some forums that was because of the switchable graphics, than upgraded ubuntu 12.04 by setting to "nomodeset". It was working, again thought to install graphics driver AMD Catalyst™ 12.8 Proprietary Linux x86 Display Driver, again after installing this, when I boot I am getting blank scree .

Can anyone help me to inatall ubuntu 12.04 along with AMD Catalyst™ 12.8 Proprietary Linux x86 Display Driver.

Any help is highly appreciated.

Hi!

okay, let's see. Can you at all log in booting from a live pendrive? If you have an Ubuntu-based PC on the side, you can easily make a bootable pendrive. otherwise, use this "recipe":

- download a live distro, Xubuntu, Fedora, anything
- enter the console
- navigate to the download location
- enter this

Quote:

sudo dd if=file.you.just.downloaded.iso of=/dev/sdb

- get coffee

the /dev/sdb is the stick (on my system), to find out where your stick resides (after plugging it in, of course) issue this

Quote:

sudo fdisk -l

to see where's what. Make sure you output to the stick and not the harddrive, dd is ruthless and destroys the data on the target drive...

Once in there, let's look at the log files. One sure way to get the graphics going is to switch to VESA, for that you'll need to either make a file (X is clever enough not to need one anymore, but if it's there, it will use it) as /etc/X11/xorg.conf

I could suggest you paste this in there:

Quote:

Section "Monitor"
Identifier "Monitor0"
EndSection

Section "Device"
Identifier "Device0"
Driver "vesa" #Choose the driver used for this monitor
EndSection

Section "Screen"
Identifier "Screen0" #Collapse Monitor and Device section to Screen section
Device "Device0"
Monitor "Monitor0"
DefaultDepth 16 #Choose the depth (16||24)
SubSection "Display"
Depth 16
Modes "1024x768_75.00" #Choose the resolution
EndSubSection
EndSection

and save it, reboot and there should be some light.

Let's go from there...

By the way, how well are you into Linux? How experienced are you? I assumed some experience, but, feel free to ask away...

By the way, welcome here
