Problem description: I was testing "fedora-development tree (aka rawhide), snapshot May1" on Power4 system plinuxt8. I did VNC-display install using network boot image, anaconda was successfully loaded and the VNC server is showing "running". I was able to connect to plinuxt8.cn.ibm.com:1 using VNC Viewer, but it displayed nothing but "big black screen". If this is not an installation problem, Describe any custom patches installed. Provide output from "uname -a", if possible: sh-3.1# uname -a Linux localhost.localdomain 2.6.16-1.2181_FC6 #1 SMP Sun Apr 30 23:03:19 EDT 2006 ppc64 unknown Hardware Environment p630:Power4 1) ensure /etc/bootptab on server points to correct inst64 network boot image 2) ensure bootlist has the network device as first 3) exit to OpenFirmware prompt with 1st boot device = network to start tftpboot add "boot vnc vncpassword=<password>" at OF prompt. 4) after anaconda started, you will be asked to connect to vnc-display desktop. 5) using vnc viewer to connect...You will meet the defect.

changed: What |Removed |Added ---------------------------------------------------------------------------- Version|FC5 |devel ------- Additional Comments From liyuanly.com 2006-06-06 01:22 EDT ------- I am changing the version to 'devel' to properly reflect that this recreates on rawhide. The status of this bug is updated; I tried to recreate on the May26 snapshot of rawhide, but it was blocked by #24198.
Reassigning to proper component as this either looks like an installer and/or kernel issue. Read ya, Phil

Please, see bug #175458. I think, this bugs are same...
----- Additional Comments From kumarr.com (prefers email at kumarr.com) 2006-10-20 11:04 EDT ------- Hello Redhat, Yes -- These bugs are the same. We have closed this bug from the IBM side as we were unable to recreate the problem in more recent releases of the FC tree.
*** Bug 175458 has been marked as a duplicate of this bug. ***
----- Additional Comments From chavez.com (prefers email at lnx1138.com) 2006-11-16 20:48 EDT ------- I hate to ask you again Lin but are we still seeing this with Beta2 (Nov11 release) ?
----- Additional Comments From shenlinf.com 2006-11-17 01:10 EDT ------- yes :(
vnc-4.1.2-7.fc6 has been pushed for fc6, which should resolve this issue. If these problems are still present in this version, then please make note of it in this bug report.
----- Additional Comments From shenlinf.com 2006-12-07 04:00 EDT ------- The problem is fixed in RHEL5 RC snap shot 2. Please change the status. Thanks.

The problem seems to have returned in F7t2. http://david.woodhou.se/badvnc.jpeg
Adding '-render' to Xvnc arguments doesn't help.
(In reply to comment #17) This regression started in vnc-*4.1.2-12.fc7 and ended in vnc-*4.1.2-15.fc7 (I think). It is caused by bad pixmap initialization. Could you give me access to test ppc64? I want test vnc-server-4.1.2-15.fc7 if this issue is solved there (I tested it on x86_64 and problem looks fixed) Regards, Adam
Fixed in 4.1.2-15.fc7
