Hi all, I'm setting up a new laptot with Advanced Micro Devices [AMD] nee ATI Seymour [Radeon HD 6400M Series] card, using radeon drivers. I'm facing an issue for wich I found a lot of references but no actual solution, so I'm asking here for some help Basically it works quite fine, except for fb. description of the issue: at boot, once fb is fired up i get a black screen, afer some usual boot messages. Connecting via ssh I can launch X and all works just fine; however with ctrl-alt-F1 the screen freezes immediately with this error in dmesg: drm:drm_mode_getfb] *ERROR* invalid framebuffer id some more debug lines: [drm:drm_helper_probe_single_connector_modes], [CONNECTOR:23:VGA-1] [drm:radeon_atom_dac_detect], Bios 0 scratch 40000 00000001 [drm:radeon_atombios_connected_scratch_regs], CRT1 disconnected [drm:drm_helper_probe_single_connector_modes], [CONNECTOR:23:VGA-1] disconnected [drm:radeon_lvds_set_property], [drm:drm_mode_getfb] *ERROR* invalid framebuffer id If I hit ctrl-alt-F7 all work just fine: screen unfreezes and I can work without other issues. Perfectly repeatable. I can provide more debug logs and data, if needed; just place me in CC: list as I'm not subscribed to this list.
