Hi, I am running fedora 20 X86_64 I have an Intel Processor: Intel(R) Core(TM)2 Quad CPU Q6700 @ 2.66GHz. I have an AMD radeon based GPU card : Advanced Micro Devices, Inc. [AMD/ATI] RV535 [Radeon X1650 PRO] (Secondary) (rev 9e) I have two monitors : ACER Technolgies – on DVI-0 (1920x1080) Viewsonic Corporation on DVI-1 (1920x1200) They are (were!) driven by the radeon module : lsmod :- ..... radeon 1496040 2 ..... i2c_algo_bit 13257 1 radeon ..... drm_kms_helper 89555 1 radeon ttm 80807 1 radeon ..... drm 296901 5 ttm,drm_kms_helper,radeon /var/log/messages shows: radeon 0000:01:00.0: VRAM: 512M 0x0000000000000000 - 0x000000001FFFFFFF (512M used) radeon 0000:01:00.0: GTT: 512M 0x0000000020000000 - 0x000000003FFFFFFF [drm] Detected VRAM RAM=512M, BAR=256M [drm] RAM width 128bits DDR X server log shows: [ 88.037] (II) Loader magic: 0x80dd00 [ 88.037] (II) Module ABI versions: [ 88.037] X.Org ANSI C Emulation: 0.4 [ 88.037] X.Org Video Driver: 14.1 [ 88.037] X.Org XInput driver : 19.2 [ 88.037] X.Org Server Extension : 7.0 [ 88.037] (II) xfree86: Adding drm device (/dev/dri/card0) [ 88.040] (--) PCI:*(0:1:0:0) 1002:71c1:174b:0840 rev 158, Mem @ 0xd0000000/268435456, 0xfdaf0000/65536, I/O @ 0x0000ae00/256, BIOS @ 0x????????/131072 [ 88.040] (--) PCI: (0:1:0:1) 1002:71e1:174b:0841 rev 158, Mem @ 0xfdae0000/65536, BIOS @ 0x????????/65536 .... ....

I understand UMS is User ModeSetting – which according to a quick browse of the source for the radeon module means CONFIG_DRM_RADEON_UMS is not set. Then I came across comments to the effect that this has been deprecated (a mysterious word akin to legal-speak!) presumably replaced by KMS. Has anybody got any clues how I can get the radeon driver loading and working again? Or even if its a bug whether it will soon be fixed?
