[gentoo-user] HD7870 AMD Catalyst no framebuffer console
Hi all, I have a video card HD7870, I tried install the AMD Catalyst driver ~amd64 in portage, it works well under X. But when I press ctrl+alt+F1, the screen is blank?? Although I googled this problem I add nomodeset and radeon.modeset=0 video=uvesa to the kernel cmdline in /boot/grub/menu.lst, it didn't work at all. What can I do to solve this? Liu Yang

IIRC fglrx does not support KMS, hence no framebuffer. The radeon parameters are of no use in this case; in order for the proprietary driver to work properly, the open source module must be blacklisted. So instructing the radeon module makes little sense. Please correct me if I got any of these wrong; haven't used the binary blob for about 2 years myself, the memory is slowly fading.

So instructing the radeon module makes little sense. correct, don't load the radeon module. You can also disable the Direct Rendering Manager (CONFIG_DRM). For framebuffer on my machine I use CONFIG_FB_EFI, but CONFIG_FB_VESA should work too. I'm not sure about CONFIG_FB_RADEON
