On a new ASUS AMD-APU, running Win 10, I created a dual boot with SuSE Leap 42.1, all is well, until after install and I get the error - Radeon - ‘Can’t find backlight controller’. It boots only to a command line. I try startx and it bombs. I have googled and tried sudo zypper in fglrx and also tried to add nomodeset in a boot parameter, but nothing works. I understand the issue I believe to be is to remove any drivers coming from the install as the drivers are already in the kernel core, so I think. What I need help with is exactly how I can use the command line from SuSE Leap 42.1 on my ASUS A555D laptop with Radeon graphics R8 M350DX to fix this whether it is to install, uninstall, or set the parameters correctly in GRUB, in simply laymans terms. If i need to bring back data and config info, please let me know where I need to run what command lines.
Oddly enough, I have other AMD/ATI/Radeon cards and run SUSE 12.2 and Leap on with no issues.
On the laptops sticker, it say’s Radeon Graphics R8 M350DX 2GB and the CPU, in in his case the APU the Windows OS identifies it as:
AMD FX-8800P Radeon R7. The GPU and CPU are on the same chip.
After installing Leap 42.1, I booted, and during boot, in complained of 'Radeon - Can’t find backlight Controller, then allows to login from command line only. I tried startx and get a screen full of errors and it ends back to a goofed command line that complains about not finding the backlight controller, and then I have to boot because it takes no input from the keyboard.
While at a good command line (before doing an attempt at startx), I keyed in
sudo zypper in fglrx
and it goes through getting the repositories, and then reports that fglrx is not found
What else can I try to report back to give a better picture as to what I’m facing? I get the impression that I just need to hit the right repository, that has the right driver, with the correct install command line and all will be well.
I’m seeing that Leap 42.1 is based on Linux Kernel 4.1, and that Ubuntu Desktop 15.1 is based on 4.2, which mentions in its release notes that 4.2 newly supports the newer AMDGPU’s, interesting. Looks like this APU I’m running isn’t really supported by Leap just yet, and this would explain why I can’t seem to get a GUI to gen up.
