The radeon/nouveau and libstdc bug is fixed in the daily build. It
should have been backported for the 1.10.2 release, but it wasn't.

I am very surprised that you had problems with the NVIDIA driver.
Historically, it has been less buggy than the open source driver and
much faster, which is why I strongly recommend using the NVIDIA
driver. See <a

The NVIDIA driver is at least twice as fast as the open source one,
and usually even faster. The results are similar for older graphics
cards. The NVIDIA driver also supports OpenGL version 4.5, while
nouveau is back somewhere before 4.2 (3.3?).<br>

<div>Recently I used Chimera for a internship/volunteer work

<div>(Error from the NvIdia machine) and would not load r600.
However both had the same fix, that seemigly works by removing
the file /Chimera64-1.10.2/lib/libstdc++.so.6, I renamed it to
libstdc++.so.6.bak in case I might need it, but it works on
both machines now. It seems as some older libs are colliding
with mesa drivers, and casung them to break, and removing this
fixes the problem. Its been documented before with other
programs here, where the fix is simular. <a

<div>I also found that in the chimera mail I found, it was
recommend to update some drivers, or Nvidia drivers, however,
nvidia drivers for linux tend to break the system a lot or
cause other problems.</div>
