Description Nikita Krupenko 2015-10-04 21:11:12 CEST

I have laptop with AMD A8-5557M APU (Radeon HD 8550G) and discrete videocard Radeon HD 8750M.
When I try to boot LiveDVD image (on a USB stick), it boots up to X an then reboots. If I use EFI boot, I also see garbage on a screen, may be something is broken in videomodes.
I can boot the system if I add either nomodeset or modprobe.blacklist=radeon, which forces system to use fglrx video driver. In this case all starts fine, though I still see garbage on the screen during boot in EFI mode.

This may be related to #16901. When I boot with one of the options specified above, I see in the xorg.conf different drivers for videocards, as in bug 16901.

I also should note, that Installer DVD (not Live) with EFI boots, but I see garbage on screen (may be something with videomodes). In BIOS mode all fine.

@ nikita

Did you see the same in the Mageia 6sta1 isos?

I'll check with the new iso.

Comment 4 Nikita Krupenko 2016-11-11 13:56:35 CET

I checked and I can't even boot the system with the new iso. Seems like Bug 18322 blocks this one.

Comment 5 Nikita Krupenko 2017-04-05 12:24:14 CEST

Checked with the MGA6 sta2 image in EFI mode.
Now boots fine both in Live mode and in installer if I select open-source drivers in the boot menu (default).
With proprietary drivers doesn't work though, even when I add modprobe.blacklist=radeon boot parameter.

Comment 6 Martin Whitaker 2018-03-12 22:15:25 CET

AMD stopped supporting 'fglrx', so there is no proprietary driver for AMD GPUs in Mageia 6. So I think we can close this as fixed.
