Hi All, since quite a while, the RADEON frame buffer driver does not longer initially sets the native screen resolution for the console, which is 1920x1200 here, but decides on 1024x768 instead. The display uses a display-port connector, which might be the particularity. As you see, this is a stock debian kernel, but I have the same effect with locally compiled kernels. Earlier kernels up to late 3.x worked well in this respect, so do drivers for other hardware. Thus I assume that the effect is unwanted. I can not work around the problem, since mode setting is not longer available. I'm not sure what information you'd need beside the ones included below, but I would gladly provide them on request and/or could try out a patch if necessary. Kind regards Lars -- --- $ lspci 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.[AMD/ATI] RV620 GL [FirePro 2260] $ journalctl -b | grep radeon|drm|fbcon : Linux version 4.3.0-1-amd64 (debian-kernel@xxxxxxxxxxxxxxxx) : [drm] Initialized drm 1.1.0 20060810 : [drm] radeon kernel modesetting enabled. : [drm] initializing kernel modesetting (RV620 0x1002:0x95CF 0x1002:0x2143). : [drm] register mmio base: 0xE0200000 : [drm] register mmio size: 65536 : radeon 0000:01:00.0: VRAM: 256M 0x0000000000000000 - 0x000000000FFFFFFF (256M used) : radeon 0000:01:00.0: GTT: 512M 0x0000000010000000 - 0x000000002FFFFFFF : [drm] Detected VRAM RAM=256M, BAR=256M : [drm] RAM width 64bits DDR : [drm] radeon: 256M of VRAM memory ready : [drm] radeon: 512M of GTT memory ready. : [drm] Loading RV620 Microcode : radeon 0000:01:00.0: firmware: direct-loading firmware radeon/RV620_pfp.bin : radeon 0000:01:00.0: firmware: direct-loading firmware radeon/RV620_me.bin : radeon 0000:01:00.0: firmware: direct-loading firmware radeon/R600_rlc.bin : [drm] Internal thermal controller with fan control : [drm] radeon: power management initialized : radeon 0000:01:00.0: firmware: direct-loading firmware radeon/R600_uvd.bin : [drm] GART: num cpu pages 131072, num gpu pages 131072 : [drm] PCIE GART of 512M enabled (table at 0x0000000000254000). : radeon 0000:01:00.0: WB enabled : radeon 0000:01:00.0: fence driver on ring 0 use gpu addr 0x0000000010000c00 and cpu addr 0xffff8800c9c81c00 : radeon 0000:01:00.0: fence driver on ring 5 use gpu addr 0x00000000000521d0 and cpu addr 0xffffc900010121d0 : [drm] Supports vblank timestamp caching Rev 2 (21.10.2013). : [drm] Driver supports precise vblank timestamp query. : radeon 0000:01:00.0: radeon: MSI limited to 32-bit : radeon 0000:01:00.0: radeon: using MSI. : [drm] radeon: irq initialized. : [drm] ring test on 0 succeeded in 1 usecs : [drm] ring test on 5 succeeded in 1 usecs : [drm] UVD initialized successfully. : [drm] ib test on ring 0 succeeded in 0 usecs : [drm] ib test on ring 5 succeeded : [drm] Radeon Display Connectors : [drm] Connector 0: : [drm] DP-1 : [drm] HPD2 : [drm] DDC: 0x7e60 0x7e60 0x7e64 0x7e64 0x7e68 0x7e68 0x7e6c 0x7e6c : [drm] Encoders: : [drm] DFP1: INTERNAL_UNIPHY : [drm] Connector 1: : [drm] DP-2 : [drm] HPD4 : [drm] DDC: 0x7e20 0x7e20 0x7e24 0x7e24 0x7e28 0x7e28 0x7e2c 0x7e2c : [drm] Encoders: : [drm] DFP2: INTERNAL_UNIPHY : [drm] fb mappable at 0xD0355000 : [drm] vram apper at 0xD0000000 : [drm] size 3145728 : [drm] fb depth is 24 : [drm] pitch is 4096 : fbcon: radeondrmfb (fb0) is primary device : radeon 0000:01:00.0: fb0: radeondrmfb frame buffer device : [drm] Initialized radeon 2.43.0 20080528 for 0000:01:00.0 on minor 0 -- To unsubscribe from this list: send the line "unsubscribe linux-fbdev" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
