Hello. I upgraded my kernel from 2.6.29 to 2.6.30.4. I was using intel KMS to get framebuffer console on my laptop. With 2.6.29 i got full 1280x800 resulution. Also console used whole space of my LVDS screen.
But after upgrade to 2.6.30.4 i got console only to 1024x768 but screen resolution is 1280x800. So i have unused place in right and bottom of my screen. But with framebuffer applications i can use this space. (like fbtext of my own, because I am using fb_var.xres_virtual). What has changed: Before I had not TVDAC output, nor modes for it like now. (modeprint, modetest output added on the end). I have looked in kernel source (drivers/gpu/drm/i915/intel_fb.c) and there is something like intelfb_single_fb_probe: /* Smallest mode determines console size */ /* but largest from memeory allocation dimension */ In this code system looks from all crtcs and look for desired_mode and gets smallest for console. So I assume that from TVDAC its desired_mode is 1024x768 so fb_width is changed to 1024. But I have no TV connected, but connected state is not checked here. What should I do to get whole console size usage (e.g. 1280x800), like before with no TVDAC. Thanks, Peter. modeprint: Starting test Resources count_connectors : 3 count_encoders : 3 count_crtcs : 2 count_fbs : 0 Connector: 1-1 id : 5 encoder id : 0 conn : disconnected size : 0x0 (mm) count_modes : 0 count_props : 2 props : 1 2 count_encoders : 1 encoders : 6 Connector: 7-1 id : 7 encoder id : 8 conn : connected size : 330x210 (mm) count_modes : 1 count_props : 2 props : 1 2 count_encoders : 1 encoders : 8 Mode: "1280x800" 1280x800 60 Connector: 6-1 id : 12 encoder id : 13 conn : disconnected size : 0x0 (mm) count_modes : 4 count_props : 7 props : 1 2 20 16 18 17 19 count_encoders : 1 encoders : 13 Mode: "1024x768" 1024x768 30 Mode: "800x600" 800x600 30 Mode: "848x480" 848x480 30 Mode: "640x480" 640x480 30 Encoder id :6 crtc_id :0 type :1 possible_crtcs :3 possible_clones :1 Encoder id :8 crtc_id :4 type :3 possible_crtcs :2 possible_clones :2 Encoder id :13 crtc_id :3 type :4 possible_crtcs :3 possible_clones :4 Crtc id : 3 x : 0 y : 0 width : 0 height : 0 mode : 0x804b254 gamma size : 256 Crtc id : 4 x : 0 y : 0 width : 0 height : 0 mode : 0x804b254 gamma size : 256 Ok modetest: trying to load module i915...success.
