"I will not try other browsers because changing the browser is not a 
solution. I believe that the problem must be related to graphics 
management at a kernel level.

The serious bug that afflicts this system is certainly not repeatable 
for any generic Ubuntu system, but probably can be repeated with similar 
system configurations havin intel integrated graphics 85x etc. To get 
this system past a blank screen after boot of Lucic clean install I had 
to apply the first workaround at 
https://wiki.ubuntu.com/X/Bugs/Lucidi8xxFreezes .

PS: I had high hopes on 10.04 LTS but now I feel like almost giving up 
this release as well. The former 9.10 was catastrophic for many of our 
systems at work and at home. The older 8.04 LTS was a candidate but has 
very limited functionality on many devices that we need. So the 
trade-off is hopeless: Older Ubuntu versions do not work with required 
devices and newer versions are unstable."

But it's a free hopelessness...
