Might be worth a try to get in line with Mint:
What do you think francois?

Well, in American lingo it's called covering all the bases.

I take any talent to address a problem where I can find it and give back free like converting apps into xzms to upload the archives so others -- especially newbies -- needn't go through the same misery trying to get them to work. No need to spread the grief, especially when you're trying to help make Porteus even more user friendly.

In Linux (in porteus?), some background images and those on image viewers show that rainbow halo effect sometimes found when high resolution images are being shown in low resolution on other machines.
@bogomips and Jim:
Is this only with some software only or all of them.
So far it's just hi-rez background images and some rendered on USM viewers. I think your hz remark is on the mark and I'll test that out shortly once I see how to do that on the R31 outside Porteus since there seems no such hz control on Porteus. If Mint can tap such a switch there must be a way!

Get the frequency of your screen under windows:

I could not find it on the net with R31 display specs.
We will adjust it accordingly with gtf and xrandr commands under linux if this is the problem. Actually the xrandr output gives 60 Hz, we might try another frequeny, but we have to make sure your screen supports it,
if we do not want to damage it. However, this was an issue for older display, and should not be one for more recent ones. For
gtf, see:

Additionally, this might do some good you have to try to alter colors with the gamma command with xrandr. There is also a mention about brightness:

Digging in the gamma specification for xrandr might give us
some results.
Jim please try the following command line for your thinkpad:
Code: Select all
xrandr --output LVDS1 --gamma 1.05:1.15:1.136
Tell me if its any better.
