VNC non functional with -depth 24
Last modified: 2013-04-30 19:35:54 EDT
Description of problem: VNC non functional with -depth 24 Version-Release number of selected component (if applicable): vnc-server-4.1.2-16.fc7 How reproducible: Always Steps to Reproduce: 1. Set /etc/sysconfig/vncservers to: VNCSERVERS="1:vnc" VNCSERVERARGS[1]="-geometry 1024x768 -depth 16" 2. Issue "service vncserver start" command. 3. After a few moments server is dead. Actual results: Server dies with the following in the VNC log file: Xvnc Free Edition 4.1.2 Copyright (C) 2002-2005 RealVNC Ltd. See http://www.realvnc.com for information on VNC.

Additional info:
There is a typo above in step 1, it should read "-geometry 1024x768 -depth 24". "-depth 16" does work for twm (but not for WindowMaker, see bug# 242280).
bug# 242280 looks like different issue (bad handling of RENDER extension looks for me). You could try http://people.redhat.com/atkac/test_srpms/vnc-4.1.2-18.fc7.src.rpm which has 24bit support and tell me your opinion. Regards, Adam
vnc-4.1.2-18.fc7 runs with "-depth 24" but there are other problems with this version. For example, you cannot run GNOME applications like gedit. From xterm: zaurak$ gedit The program 'gedit' received an X Window System error. This probably reflects a bug in the program. The error was '163'. (Details: serial 372 error_code 163 request_code 150 minor_code 4) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) zaurak$ No GNOME application I have tried will run under WindowMaker or twm. This worked fine in FC6, and works fine in Fedora 7 using VNC from FC6 (vnc-server-4.1.2-3.fc6 appears to work perfectly in F7).
Another odd thing; with vnc-4.1.2-18.fc7 in twm, when resizing or moving a window, you don't get the wire-frame outline that is normal for twm. I have moved back to vnc-server-4.1.2-3.fc6 and twm/WindowMaker work perfectly. In twm, wire-frame when moving & resizing is back etc. Can you not just re-release the FC6 version as an update to F7 ? It seems to just work.
(In reply to comment #4) Hm :) Much development have been done on Xvnc so better is find and fix bugs. Adam
I've done next version and 24bit depth works perfectly also with gnome applications. Could you please test it? This could be final 24bit F7 version. http://people.redhat.com/atkac/test_srpms/vnc-4.1.2-17.1.fc8.src.rpm Thanks for your cooperation, Adam
Adam - build errors (I have no idea how to fix them) as follows: Patch #14 (vnc-s390.patch): + patch -p3 -b --suffix .s390 -s 1 out of 1 hunk FAILED -- saving rejects to file hw/xfree86/os-support/linux/lnx_video.c.rej 1 out of 1 hunk FAILED -- saving rejects to file hw/xfree86/os-support/misc/SlowBcopy.c.rej error: Bad exit status from /var/tmp/rpm-tmp.91873 (%prep) . [snip] . Bad exit status from /var/tmp/rpm-tmp.91873 (%prep) Can you post binaries or fix the src rpm ? I will be able to test over this weekend if so.
You could download your architecture from http://koji.fedoraproject.org/koji/taskinfo?taskID=30862 . Adam
Adam, you src above was labeled "fc8" while the link in comment# 8 points to "fc7" . However I installed it and it seems to work OK. My /etc/sysconfig/vncservers file look like this: VNCSERVERS="1:vnc 2:vnc 3:vnc" VNCSERVERARGS[1]="-geometry 1280x1024 -depth 24 -extension Composite" VNCSERVERARGS[2]="-geometry 1280x960 -depth 24 -extension Composite" VNCSERVERARGS[3]="-geometry 1024x768 -depth 24 -extension Composite" It seems to work OK so far with twm and WindowMaker (GNOME apps run OK too). I will test further over the weekend.
(In reply to comment #9) > Adam, you src above was labeled "fc8" while the link in comment# 8 points to > "fc7" . However I installed it and it seems to work OK. Currently fc7 & fc8 versions are same. Only problem was that someone made change in main X source about two days ago and "s390" patch do something with changed code so looks like you don't have latest xorg-x11-server-source package (>= 1.3.0.0-7 it's possible that update wasn't pushed yet) :) A
vnc-4.1.2-18.fc7 has been pushed to the Fedora 7 stable repository. If problems still persist, please make note of it in this bug report.
