[Bug 1568211] Re: no UMS support in radeon module
I have an AMD A10-5800K (HD 7660D graphics) and have not been able to boot with 'nomodeset.' I get an error message, "ERROR: no UMS support in radeon module," and then in a few seconds the screen fades to black. I've had no problem booting from my USB with 14.04 LTS installed, or from the 15.10 LiveCD, but 16.04 seems to be hopeless. I can't even get a log of what's going on, because booting doesn't complete. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1568211 Title: no UMS support in radeon module To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1568211/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have an A8 3820 AMD cpu (HD 6550 graphics) I have the same problem. First I want to say that I have been booting a usb hdd since 16.04 alpha. when I booted kernal 4.4.0-10 no problem, but I then booted to 4.4.0-12 that's when the problem started. Then I waited for the release of 16.04, there was no change. I just booted the live dvd using nomodset option and the screen showed an error "no ums support on radeon module." I don't have any other driver installed except what's in the kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1568211 Title: no UMS support in radeon module To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1568211/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1568211] Re: no UMS support in radeon module
I am facing the same issue. I have upgraded from Xubuntu 14.04 to Xubuntu 16.04 and I was greeted with a black screen just after my first reboot. I use a Radeon HD 5430 card with two monitors. Incidentally, I had to switch off one of them so that the Live USB from which I installed the upgrade would work. The problem, though, started with the reboot. This is the output of my uname -a: Linux tiramisu 4.4.0-21-generic #37-Ubuntu SMP Mon Apr 18 18:33:37 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux There are three ways in which I can "start" my computer: * Normal boot, which ends in a black screen. * Recovery mode, which, after selecting "continue boot", generates errors such as "*ERROR* no UMS support in radeon module!" above, defaults to VESA module (and poor resolution), and cannot manage two screens. I enclose the Xorg.1.log file for this method. * Recovery method and deleting the nomodesetting kernel option. After selecting "continue boot", I get a perfectly working environment: radeon module works, etc. I enclose the Xorg.0.log file for this method. ** Attachment added: "Corresponds to a "clean" boot" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1568211/+attachment/4645367/+files/Xorg.0.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1568211 Title: no UMS support in radeon module To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1568211/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have a computer with AMD A8-6600K APU processor with a module Radeon HD Graphics (HD 8570D) Booting a new Ubuntu 16.04 from a LiveDVD the monitor receives no signal and apparently nothing happens, except the running of the DVD- player. However, booting with the option Nomodeset is successful, only a message shows up that no UMS support is present in the Radeon module.

Spooky. This morning I booted normally. I had a kernel upgrade to 4.4.0.18.34 early evening on 8 Apr which did have this problem. Since then there has been no updates. To the best of my knowledge I made no changes to the hardware. But there I am with a working system. Very spooky. I've attached the drm relevant messages from dmesg for information, just in case. ** Attachment added: "DRM kernel message on boot." https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1568211/+attachment/4631532/+files/drm.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1568211 Title: no UMS support in radeon module To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1568211/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I am also affected by this bug after upgrading to Xenial and trying to use radeon KMS. My system will only boot with `nomodeset` or `radeon.modeset=0`. Futhermore, attempting `sudo modprobe radeon modeset=1` after booting with `nomodeset` results in the same error state: screen goes blank, monitor's "No signal detected" message appears. Sometimes the machine reboots, but not always. I have a Radeon HD5770 card.
