[Bug 1273005] [NEW] Unity may use "export UNITY_LOW_GFX_MODE=1" option in low hardware or VM

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Trying to run Ubuntu in a low hardware (any hardware weaker than one
core 2 duo, i think) or in a virtual machine is painful. Even in a new
hardware, with core i7 for example, it is slow with Unity, if it uses
Intel graphics onboard.

There is a simple workaround, put "export UNITY_LOW_GFX_MODE=1" in
.xprofile, in your home. If the hardware is weak, ubuntu could run Unity
with this option. This greatly improves performance.

"Linux for human beings", so, only for human that have new and top
hardware? I know a lot of people that have a modest hardware (here in
Brazil is common to have a hardware from 3 or more years ago).

Yeah, i know that there are xubuntu and lubuntu, but people normally
knows Ubuntu, not others flavors. And as i said before, Unity is slow in
new hardware too (if you don't have a nvidia or amd graphic card
installed...).
