Thank you for sharing your kernal configuration. Comparing it to mine, I have found only two differences. Namely, my kernel configuration had: CONFIG_DRM_VGEM=n (you had "y" here) CONFIG_DRM_UDL=n (you had "m" here) I consired the second one irrelevant. So, I have changed the first one and recompiled everything you mentioned. (VIDEO_CARDS variable in my make.conf alsowas the same.) However, after reboot, I have got the same startx error message. Looking onto dmesg, I found the following messages related to Radeon video card: [1.096815] [drm] radeon kernel modesetting enabled. [1.097070] [drm] initializing kernel modesetting (RV740 0x1002:0x94B3 0x1002:0x0D00 0x00). ... [1.098286] [drm] radeon: 512M of VRAM memory ready [1.098341] [drm] radeon: 1024M of GTT memory ready.

[1.098655] radeon 0000:01:00.0: Fatal error during GPU init [1.098710] radeon: finishing device. I have not included RV730_pfp.bin to EXTRA_FIRMWARE kernel variable. (And should not, according to the documentation.)
