 |
|
I am trying to install Gentoo on one of my laptops.
It appears that my graphics card is not being used and I have this probably 640x480 screen size with only the terminal.
| Code: | # lspci | grep VGA
01:05.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RS780MC [Mobility Radeon HD 3100] |
I am using the gentoo-sources-3.18.7
| Code: | Device Drivers -->
..... Generic Driver Options -->
.......... [ * ] Prevent firmware from being built
.......... -*- Userspace firmware loading support
.......... [ * ] Include in-kernel firmware blobs in kernel binary
..... Graphics support -->
.......... <*> /dev/agpart (AGP Support) -->
............... <*> AMD Opteron/Athlon64 on-CPU GART support
............... <*> Intel 440LX/BX/GX, I8xx and E7x85 chipset support
..... Direct Rendering Manager -->
.......... <*> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support)
.......... <*> ATI Radeon
............... [ ] Enable userspace modesetting on radeon (DEPRECATED)
..... Frame buffer Devices -->
.......... -*- Support for frame buffer devices --> |
| Code: | # cat /etc/portage/make.conf | grep VIDEO_CARDS
VIDEO_CARDS="radeon" |
I also have the linux-firmware installed
Not sure what I'm missing :/

Maybe the radeon module isn't loaded. Please show
| Code: | | dmesg | grep radeon |

You are possibly missing the firmware for the card. Installing either sys-kernel/linux-firmware or x11-drivers/radeon-ucode is only enough if radeon is built as module.
If it is compiled into your kernel, additionally set
| Kernel .config: | CONFIG_EXTRA_FIRMWARE="radeon/R600_rlc.bin radeon/RS780_uvd.bin"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware" |
