Hey folks, haven't been around for quite a while. - That's a good sign regarding LTSPs stability and performance. - A big thanks for all the efforts of the last years!
In my home-setup I came across a weird phenomen that costed me my day,
yesterday. The good news is, that I solved it. - However, I'd like to
post this in order to
- understand the issue, and
- enable others not to tap into the same trap
Setup: A Debian Jessie Server (64bit) with 4 NeoWare CA22 clients,
either with 256 MB or 1 GB RAM; several types of display (19' CRT, 17'
LCD, 19' LCD, 22' LCD).
Two stations were working with X (merkur & mars -- the ones with the 19'
displays, one with 256 MB, the other with 1GB), venus & erde, the other
two, simply got no picture with X.
Here is the relevant section from my lts.conf:
Old Config - no longer working on VENUS and ERDE
New Config - now is all fine again
[neoware]
# XSERVER = vesa
SOUND = True
SOUND_DAEMON = pulse
VOLUME = 90
PCM_VOLUME = 90
MIC_VOLUME = 100

1. It seems that under certain circumstances, it is not necessary to
specify "XSERVER = vesa" with the NeoWare CA22. - Why this is so, I have
no clue. - Possibly that the other required settings imply for some
reason the vesa server? - If someone's got a hint on that, this would be
interesting. By the way, would there be any other Xserver working on
this client alternatively?
2. On ERDE, I also tried to set the mode woht the XRANDR options.
However, I went back to the "classic" options, because I got a bigger
virtual desktop and no way to move the screen window within it. (I had
only the upper left corner of a felt 1920x1080 resolution. - Is there
another option to specify this? - Anyhow, this behavior was wired and
now I got a workaround.
3. On VENUS, I specified a modline - as it appears that it is not
necessary I commented it out. However, my question is, whether the
syntax is correct. I didn't find any examples for "XRANDR_NEWMODE_0" on
the net.
Thanks a lot folks, and have a nice day.
Stefan.
