https://bugs.freedesktop.org/show_bug.cgi?id=93405 --- Comment #10 from Elmar Stellnberger --- Good news: I can now set various 3840x2160 modes without making nouveau halt or crash (It may still hang after a heavy reconfiguration session though). The only drawback about it is that my displays (AOC u2868pqu, Samsung flat-tv) will stay dark (3840x2160 non-interlaced) or in a fact show a 2560x1600 mode when I try to set a 3840x2160 interlaced mode (the monitor does not claim to support interlaced modes by its EDID though). Tested with various modelines as well as the modeline suggested by my xorg.conf. Would anyone have a look whether it should be possible to achieve 3840x2160 with this hardware configuration (Xorg.0.log is available; decoded edid will come shortly.)? -- You are receiving this mail because: You are the assignee for the bug.
