Machine 1: HP ZBook 15 configured to serve as a Wi-Fi hotspot. Network

I will most likely test it soon.
However, later after the bug rerport I discovered, that ubuntu supports also
creation of WPA/WPA2-secured hotspot and, surprisingly, this more secure
network provides full speed, about 10 times faster than the WEP hotspot.

Yes, it is still an issue on ubuntu 13.10. (No proprietary NVidia driver
installed.) I will test the problem on the latest development version of
ubuntu.
The issue is worse than you might expect. I often need to read and edit
documents and those use a white background (typically PDF documents).
ebutler, thanks for the workaround, I will try it.
In the meantime I tested at least the live version of the latest development

Yet another test and verification: I subsequently inserted the DVD disk
into two other PCs (desktop ones). The first one (an old PC with Intel
Core Quad) failed to boot completely, just showing some I/O errors. The
other PC (Intel i7 3930K Extreme) booted only to text console. Both use

I confirm that the bug still exists in the latest development version of
