Steam barely usable in old notebook

[FurretUber]

Hello

I have installed Steam in my notebook and Steam is being very problematic on it. What happens: many graphic bugs, it makes Steam nearly unusable. This images gives a idea of the issue:

Nearly every button, image or text appears as white, gray or black blocks. This is not new to me:

Stellarium: 0.11.6 functional, anything above shows a white screen
XMind: refuses to open
Firefox: gray block in address bar (solved changing gfx.xrender.enabled to false or using a specific theme)
Google Earth: a dark sphere (Earth) appears and I can see only the borders

The notebook is a Asus M2400N, a 2003 notebook. It has 1248 MB RAM, an Mobile Intel® 855GM Chipset, an Intel® Pentium® M Processor 735 (Warning: pae forced!). The 855GM supports up to OpenGL 1.3 (I believe this is what causes all the issues).

My goal is not to play games on it. I wanted to make the Steam interface functional so I could chat with my friends and start servers on it. Is there a option which makes a simpler interface load, as the Firefox option/theme or Stellarium older version?

PS.: Starbound server is running on it right now. The game don't open due to lack of OpenGL 2 (it loaded everything and crashed. I had a false hope).

Thank you

Do you know what the gpu is? You might want to see about installing a newer driver for it.

It is a Extreme Graphics 2, Mobile Intel® 855GM Chipset ( https://en.wikipedia.org/wiki/List_of_Intel_graphics_processing_units#Second_generation )

The most recent driver available in Intel site is from 2005. They are labeled only to Red Hat Linux 3.0, I am using Lubuntu 16.04. There are files to the X server. I believe that if I install that, the video will no longer function because they are too old (happened with IrDA, losing video capabilities would be a bit worse).

The system is with the most recent stable versions of all its software.

About the different appearances to Steam (skins, themes, another name?), is there one that do not demand much video? If there is one that makes Steam looks like GTK or qt4 or do not need OpenGL above 1.3 it would be enough to solve this issue.

PS.: is there a good site to search for these themes?
