Pinned topic ClearCase Font differences between LINUX and UNIX workstations

‏2006-05-03T13:25:15Z |
There is some type of font incompatibility when running xclearcase on Linux, with the display set to an HP-UX workstation. A lot of the Clearcase windows have garbage in them, which makes work difficult, if not impossible. I can play around with the fonts on HP-UX to get rid of some of these problems, but not all of them.

Now, here's the strange part:
If I run xclearcase directly on the Linux PC (i.e., I log into the main console), then Clearcase works fine.
If I log on to my HP-UX workstation and then log into our Linux server, set the DISPLAY back to my HP-UX workstation, and start xclearcase, then I get the "garbage fonts" problem.
However, if I start a "failsafe" session on my HP-UX workstation, log into the Linux server, and then start xclearcase...everything works perfectly.

The difference between regular and failsafe sessions on HP-UX is that the regular session uses CDE and the "dtwm" window manager, while the failsafe session uses a barebones X11 display and the "mwm" window manager.

Apparently there is some known incompatibility between PC Linux fonts and the Unix fonts accessed by "dtwm": I came across a Rose release notes manual from 2001 that mentioned that Rational ships a special set of fonts with Rose that are compatible on both Linux and Unix.

So here's my question: is there a special set of fonts shipped with xclearcase to ensure compatibility between Linux and Unix windows display managers?

    works just fine for me.
    what HP-UX version and what Lunix version is this?
    clearcase likes a setting of LANG=en_US (without the iso or extended
    stuff that Linux sometimes has).
    we had to set that to get the CC GUI working nicely with any (remote)
    display on Linux.

      Hi Martina.
      You were absolutely right. Originally we were told to setup our .bashrc file on Linux to export LANG=en_US.rso885915. As soon as I changed it to export LANG=en_US, I could export my display without the garbage font.
      Thank you so much,
      Cathy
