Introduction to Post one
Members may have read this before downloading Nemesis or afterwards. Its the afterwards that leads to two main permutations
variant one ) They failed to update thru pman or pacman or applet
variant two ) They have updated mhwd or libgl , received an error message they did not understand.....see Post two for that discussion
Note this tutorial has nothing to do with choosing another video driver package specific to your chipset. If you have a graphical screen and working keyboard and mouse you are at least halfway there. If you have no graphical screen or incorrect input devices please start a new thread as answers will vary due to different hardware please.
So first we open a terminal and try to discover if our current system is correctly configured for the Xorg environment.
with root powers means if you login as guest either prefix each command below {with the exception of step (3)} with sudo or gain root powers for that session without worrying about using the root's environment settings by
Code: Select all
sudo su
Code: Select all
glxgears
Error: couldn't get an RGB, Double-buffered visual
glxinfo
name of display: :0.0
Error: couldn't find RGB GLX visual or fbconfig
Start Fixing
Now if you have already done (1) leap to (2) and if you have done (2) leap to (3)
1) setup-pman with root powers, is the top command and (2) the bottom 2 commands in next code box.
2) fixup dcadec with root powers
Code: Select all
setup-pman
rm -rf /usr/lib/libdcadec.so.0
pacman -S dcadec
3) Now we attempt to fix glx stuff with root powers
Code: Select all
mhwd-gpu --setgl mesa
killall Xorg
otherwise login as guest.....then open a terminal and repeat
Code: Select all
glxgears
Those high numbers you see....is because I used a timed screen shot using mtpaint. Nothing to worry about...its all good.
Note that its a terminal and a popup box that I positioned over the terminal for those who have never run glxgears before.
I have not shown a screen shot of glxinfo as its too large.
OFFTOPIC
Members should now update their system
4) Now you can update your system either thru update applet, by pman or by pacman commands.
a) applet or pacman are the same thing and will never offer modules
b) pman always offers modules see your /config/modules to tweak settings
c) For those who prefer lots of modules there are two main permutations
i) merged module with the main package and its dependencies
ii) un-merged modules so they are always separate module names
At some point in the future those who chose (ii) will find duplicate package names in their modules dir.
At some point in the future those who chose (i) may find dependency issues
That discussion belongs on another thread as well.
The best of luck on running glxgears
