I bought new computer. The Graphics card is AMD Radeon HD 6450, on Windows 7 it works fine but I try to install driver on Ubuntu, and it says that "No supported adapters detected". I downloaded the driver from here. After installing "Aditional drivers" says that driver is installed. Also my screen resolution in Ubuntu is not maximum. Can you help me install proper driver, please? Thanks in advance!
I had a similar problem, but it worked fine for the previous version of this driver: "AMD Catalyst™ 11.8 Proprietary Linux x86 Display Driver". Here are the steps to download and install it:
- Download the AMD Catalyst™ 11.8 Proprietary Linux x86 Display Driver
sudo apt-get install wget
Make it executable, if not already
chmod +x ati-driver-installer-11-8-x86.x86_64.run
Run it and follow on-screen instructions to install the driver
Hope this helps!
Do it in Debian mode:
sudo aptitude install xserver-xorg-video-ati
Or download the generic driver here:
Then go to another console (CTRL+ALT+F2), log in as root, shut down X (
/etc/init.d/gdm stop), install the driver, and restart your box.
I had the same problem, and also another one that you seem to also have at the same time: a big annoying AMD Unsupported Harware icon. As a consequence, when I tried to install Ubuntu 10.10, it froze just after the login screen and when I tried to install Ubuntu 11.10, it did not even arrive to the login screen.
Here is what I did, which solved the problem:
- using another computer, download the latest proprietary driver from ATI on the official site. In my case I had to download it from here.
- put the driver on a USB key
- reboot the computer we want to repair
- in the grub menu, select the recovery mode. This results in arriving at a command line interface. This is a proof that the Ubuntu operating system is functioning but that the problem is indeed the graphical card.
- uninstall all previous versions of
sudo apt-get remove flgrxfor example
- mount the USB key with something close to
mkdir /mnt/usbfollowed by
sudo mount /dev/sdb /mnt/usb. Another way for this little step is explained here.
- use the
cdcommand to place yourself in the folder where the downloaded driver is
- if necessary, make the driver be executable with something like
chmod +x ./ati-driver-installer-11-11-x86.x86_64.run
- execute the driver using
- follow the instructions given on the installer
- if this step did not work, you may want to try
sudo ./ati-driver-installer-11-11-x86.x86_64.run --forceinstead
- reboot your computer
Then your two problems should both be solved!
Just managed to get the above card to work on my device, running
12.04, 64-bit. I started by following the suggestions here, none of which appeared to work in my case.
The device already had a video card (Matrox VGA) which was working fine. Wanted to add this to support dual monitors. When I added the AMD Radeon HD 6450 then I would get a blank screen. (Output from the Radeon was colored pixels with no sign of response from keyboard). I would bypass the blank screen with Ctrl-Alt-F2 to get a terminal up, which displayed as expected.
command not found.
The link referred to by vikram appears no longer to be working and has moved to that referred to by Agmenor. I followed those instructions and it told me install had completed, so rebooted and same situation as above.
Ultimately I followed the instructions here on the Official Documentation which I will repeat briefly. These were run line-by-line as
### backup configuration file cp /etc/X11/xorg.conf /etc/X11/xorg.conf.BAK ### in case already installed apt-get remove --purge fglrx fglrx-amdcccle fglrx-updates fglrx-amdcccle-updates apt-get install -y fglrx fglrx-amdcccle aticonfig --initial reboot ### now check it's working ### connect video out to new video card fglrxinfo ### add video acceleration apt-get install -y xvba-va-driver libva-glx1 libva-egl1 vainfo
This is good enough for me. The boot output still goes to the Matrox and the Radeon output is blank until
