PostPosted: Mon Apr 15, 2013 3:01 am    Post subject: Gnome 3 in Fallback Mode Reply with quote

I am installing Gentoo on a computer with an AMD Radeon HD 7770 graphics card. I have followed the guide here for the configuration: http://wiki.gentoo.org/wiki/Radeon. Gnome 3 is running in fallback mode and I don't know why. I guess I don't have the drivers installed correctly but I haven't found a good guide to troubleshoot. Any help will be appreciated. I'm not sure if I should post any information so let me know what to post to help find a solution.

Thanks

It looks like that the radeon open source driver doesn't support OpenGL for your card. Maybe you can try the proprietary graphics driver (http://wiki.gentoo.org/wiki/Fglrx).

On the gentoo wiki, http://wiki.gentoo.org/wiki/Radeon, it says OpenGL 3.1 would work for my card with Mesa 9.1. So are you sure my card isn't supported?

Not sure...but on my machines i prefer the proprietary graphics driver. I had some problems with opengl and radeon in the past. So i would try flgrx.

Another idea: Are you in the video group?

Hi ideanl,

I use a 5770 with the following settings. My motherboard has a
integrated card which I sometimes use in addition. These options are green.
My Carte must use the Juniper driver. These are blue.
The main options for your HD 7770 are red. You need the "VERDE" driver.

The kernel options:
With these options, you can also build a nice splash screen.
If you do not use a splash screen now, use it anyway.

Your cart is a:
Southern Islands CAPE VERDE HD7700

These are the drivers for your carte:
radeon/VERDE_ce.bin radeon/VERDE_mc.bin radeon/VERDE_me.bin radeon/VERDE_pfp.bin radeon/VERDE_rlc.bin

If you are a user of genkernel, you can put these settings in the /etc/genkernel.conf and not in the kernel.
cat /etc/genkernel.conf wrote:

....
# Enable copying of firmware into initramfs

...



You can get the VERDE driver by:

And now the make.conf

The "radeon" is for your 7770 or my 5770.
The "r600" is for my integrated Cart. The "fbdev" is for splash screen.
The "vesa" is a fallback option if "radeon" or/and "r600" is corrupt.
I use the VMware-Player with the "vmware" Option.


/etc/portage/make.conf wrote:

# DEVICES
# ==============

You have to use the evdev driver. Without any xorg.conf file!
On this point the wiki is really outdated.


You need these programs for a working X system.
Note the Versionsnumber and USE flags!

if you're a user of grub2, you can edit this to add options to the kernel. In my case:
cat /etc/default/grub wrote:

GRUB_CMDLINE_LINUX="${GRUB_CMDLINE_LINUX}"....other options.......radeon.agpmode=8 radeon.dynclks=1 radeon.pcie_gen2=1 radeon.hw_i2c=1 radeon.modeset=1 radeon.msi=1 radeon.no_wb=1"


And if that is not enough build a file in /etc/env.d
tux env.d # cat /etc/env.d/99radeon wrote:

# http://wiki.gentoo.org/wiki/Radeon#Tuning
#Kernel parameters can be just added to the kernel commandline in grub.cfg or grub.conf.
#Environment variables could be put into a file like /etc/env.d/99radeon to have them initialized during boot.
#
R600_STREAMOUT=1 # Enable the use of OpenGL 3.0/4.2 on some cards
R600_HYPERZ=1 # Enable the use Hyper-Z on some cards
R600_TILING=1 # Enable 2D Tiling on some cards
R600_SURF=1 # Enable 2D Tiling on some cards
R600_GLSL130=1 # Enable more features of the OpenGL 3.0 API


That is to read a lot. But it works very well.
have fun
Ma

The post above didn't work either. Gnome 3 is still in fallback mode.
