font and color issues

Rick Garland — Sat, 19 Jan 2002 23:13:26 GMT

Hi all:

Working on converting my workstation from Windoze to Linux and I am almost complete except for a (I believe) a font and color issue.
I am trying to connect to NNM 6.1 on an HPUX 11.00 system from my RH7.0 Below are the errors I get.
==============================

Any ideas?

Got the font issue resolved with the xset +fp tcp/'HOSTNAME':7000 command.
NNM will now come up. But I still have problems with the colors. Listed below are the errors I get with the color issue.

Just to inform. Netscape is not running, I immediately telnet over to the HP system and rum the ovw command.

The PC I am using is the same PC that has both Linux RH7 and W2K installed and under W2K it works fine - show the 128 colors.

Just the Linux goes into monochrome.

An update -
Got the video and font issues resolved, lots of hacking with the XF86Config and XF86Config-4 files. So now I load the HPUX xfs stuff as well. However in the infinite wisdom of HP, the NNM will do all the colors and the OmniBack 4.0 will not - stuck at 256 colors. If I change the Linux color scheme to 256 colors I get the OmniBack 4.0 but the NNM is colorless. Why is HP being inconsistent with its products?

Sorry for the length of time in replying to your problem, I hope the following information will help.

Resolving the fonts issue:

It appears that HP provide all of the relevant fonts to run HP applications on Linux these can be found at http://www.hprc.external.hp.com/linux/HPFontsForLinux.tar . Login and Password for this site are xgraphic. I found that after installing this package Openview at least worked perfectly and I was able to stop using a HP9000 as a font server.

Resolving the colour issue:

Setting the DefaultColorDepth parameter within XF86Config-4 file to 32 should solve your colour problems as well, assuming your graphics card will run at the resolution you require in 32 bit colour of course :)
Unfortunately this leaves me with an issue on my machine in that glxinfo indicates the direct rendering is only active in 16 bit colour :( So if anyone has any ideas how to get colours displaying properly in 16 bit colour on a Linux box I would be interested to find out.

Kind regards,

Robert Thorneycroft

Ooops I should really check my own links before I post.

Correction to the above message the site is an ftp site and can be found at:
hprc.external.hp.com
Login: xgraphic
Password: xgraphic
cd /Linux
get HPFontsForLinux.tar

Hope this helps.
