Certain apps will not display in X

karloslambchop · 08-10-2006, 04:20 PM

Hi all... karloslambchop here.

I am running fluxbox 0.9.14 on my server and frequently use vnc to run gui apps as required. Some apps such as true image 9.1 do not run and complain of missing XRender extension?

my ongoing troubleshooting so far suggests that 'RENDER' is missing after I run, xdpyinfo.

I have also tried, dpkg-reconfigure fontconfig to no avail.

Any help as to how I can get RENDER enabled or installed would be most excellent!

I will continue to troubleshoot this while this post is up.

Thank you in advance,

karloslambchop.

i am no expert and have never heard of true image but it sounds like the app you're using wants graphics acceleration. if this is true, which i dont know, you would have to install your accelerated graphics driver (ati-flgrx nvidia-nvidia) and add the following to the bottom of your xorg.conf.

Code:

Section "Extensions"
    Option "Composite" "true"
EndSection

i hope this helps

Hi Baldy1234,

thank you for taking time to post. Sorry for the delay in getting back to you. I will look at your sugestion, however my troubleshooting has taking me to a whole new level (ha ha).

Previously I was using fluxbox through a vnc session on display:1 I since set my server to use flux on display:0 (what I would call the actual display, monitor connected etc) and the app works fine!!

This may sound bizarre, but it would appear that my vnc (xtightserver) is suppressing certain extensions of x.

I am now experimenting with using x11vnc, which claims to give the 'actual' interactive experience...

Anyway, I will post an update when I have got a little further.

respect,

karloslambchop.
