Radeon HD 3200 (onboard, RS780) Monitor Viewsonic G225f Kernel 3.16-rc3 Nonworking: [drm:radeon_compute_pll_avivo] 229500 - 229500, pll dividers - fb: 1602.7 ref: 25, post 4 Working: [drm:radeon_compute_pll_avivo] 229500 - 229500, pll dividers - fb: 240.4 ref: 3, post 5 CRTs are getting increasingly rare - perhaps a tunable for this so us fogies with 100 pound monitors can set it where it works on our system? For me, it's a trivial patch to carry forward but setting something like drm.ref_div_tweak=32 in my grub config would be easier. I haven't been able to use a kernel since commit 3216701 drm/radeon: rework finding display PLL numbers v2. -- You are receiving this mail because: You are watching the assignee of the bug.
