So my problem is this. some time ago i updated drivers. after updateing to amd driver 13.6 beta there was a problem. the brightness of the display was low and i looked it up it was a common problem, so i decided to install a older driver. now when i start catalyst control manager it says. "no amd graphics driver is installed, or the amd driver is not functioning properly." was wondering if the same problem would be when i reinstalled the newst beta and then everything was fine except the brighness. so until they fix the brighness thing i need a proper driver, but i have no clue which one. i have tried many but all but the newest beta driver have that problem.

i have hp switchable graphics. when catalyst says that, does it mean my computer is always on the intel one, or is it just a problem for catalyst?

specs:

hp dv6
win7 64 bit
amd 6770m hd graphics card.

it said

"ati catalyst mobility cannot be downloaded due to incompatible hardware/software on your computer.

the version of your graphics adapter is not supporter.

contact your notebook manufacturer fo graphics card update"

i have hp notebook with switchable graphics. that's probably the reason. if i remember correctly i have tried to download a driver from them, but it has the same problem.

Both graphics solutions are using the same video drivers, a possible explanation as to why below.

There is a chance that the software will not install as there is not enough free space on the HDD, see my canned text below;

Please note that you must always have a minimum of between 15 and 20% of a HDDs overall storage capacity available as free space or you risk the data on the drive becoming corrupt or in a worst case scenario mechanical failure of the HDD itself.
The above can render a computer inoperable if the HDD concerned has the OS on it due to the MBR (Master Boot Record) becoming damaged/corrupt, please see information @ http://pcsupport.abo...sterbootrec.htm

The quickest way to free up space on the HDD is to uninstall any software that you no longer use, old games for example, if the software has it`s own uninstaller you must use that otherwise uninstall it in the Control Panel

I noted another couple of things but will come to those in due course as you have enough to do for now.

ok, i have abaout 25% free hdd now. kinda weird to have to have 200gb free space.

It is more of an issue with smaller capacity HDDs and SSDs and the partitions on the, a 60GB partition with the OS would only require 12GB free space for example.

Have you tried uninstalling all video drivers and restarting the computer to see if it allows you to select your own video device to install.

[hullmees]

what is the proper way to uninstall? i have dot it before, but would like to know how to do that properly so i know i havent done any mistakes.

[phillpower2]

Download and save the new drivers to your desktop, create a Restore Point, go into the control panel, highlight the device that you wish to uninstall the drivers for** right click on the device, select uninstall driver, restart the computer and then install the drivers for the device that you saved earlier.

** The same steps can also be taken to uninstall a device.

i think i got catalyst to work now. much older version. no error message.

cant swich gpus, when i click on the power saving one the apply button doesnt go green. it isnt really a problem as i dont care about it.

[phillpower2]

See how it goes and if you are happy as things are.

Re updating drivers, there is a misconception among many people that you must always have the latest drivers, this is incorrect as many driver updates are released to address a known issue, if you do not have that particular issue you do not need the driver update and installing it can actually cause the user problems, some information on this @ http://lifehacker.co...date-my-drivers

Keep us posted on how you get on and good luck

thank you. if i get ay future problems i will let you know.
