Fedora Networking :: Remote Desktop Display Corruption ?

Jun 23, 2009

This is a strange problem, 2 Fedora 11 machines, both Dell's. On machine A, remote desktop is okay. On Machine B, remote desktop display is corrupt/unusable.

However, prior to upgrading to Fedora 11, both machines had Fedora 10, and, remote desktop on Machine A was corrupt and Machine B was okay.

Any idea what happened? Why did the upgrade fix one and break the other? Both machines where upgraded with Pre-upgrade. The two machines are in to separate locations, un-related to each other.

Ubuntu Multimedia :: Sony FP - No Display But Desktop Accessible Via Remote Desktop?

Mar 18, 2010

I'm working on getting my myth box hooked up to my Sony flat panel display.Originally the nvidia drivers could not read the EID, so defaulted to only 640x480 over my HDMI-DVI connection.I manually updated xorg.conf with a mode for the resolution I know the thing can handle. Suddenly there are several resolutions avaialble in nvidia-settings and it seems to be communicating with the TV, as it is now listed as a Sony FP display rather than a CRT.I'm able to change the resolution now as problem, however, lies with the TV itself. I can't seem to get it to actually display the output. I'm able to remote desktop into the box and can see Gnome logged in and everything.However nothing on the TV itself.How do I troubleshoot this? Am I missing something obvious?

Networking :: Unable To Connect To Remote Desktop

Jan 1, 2010

I installed Ubuntu 9.10 on a friends computer when Windows died on it, and though she has had relatively few problems with it, she still occasionally has problems that are really hard to impossible to fix over the phone. She is also not very knowledgeable with computers, so I was trying to guide her through setting up so I could connect to her remotely and try to figure things out, but I cannot get it to work.

I personally don't use Ubuntu on my computer, I use openSUSE and KDE so that does add to the problem, though I have used Ubuntu and Gnome a lot in the past.

I had her go to remote desktop settings and allow connections from other computers and allow other users to control the desktop, and at first I had her require confirmation and a password but it didn't work without it either. When I try to connect, it just hangs for a while then times out. I tried using KRDC and just VNC in the terminal with the same result.

There should be nothing on my side preventing a connection, but I am not positive. I am not very familiar with remote desktop outside of a LAN either. I am just trying to connect using her IP address, I don't know if there is anything else I need to include. Is there maybe some other setting that needs to be changed or maybe her DSL modem/router is blocking me though I don't know why it would, especially since P2P programs work fine.

OpenSUSE :: VNCserver Desktop Launch - Fail On KMserver

May 15, 2010

OpenSUSE11.2 (x86_64)
KDE 4.3.5

My normal windowing operations are fine. I have no problems running parallel kde desktop sessions (1 user, 1 root), switching back and forth with ease. I have been able to get vnc remote connections to work, but the only desktop environment I can get to run twm. When I try to start kde it fails with:

startkde: Starting up...
kdeinit4: preparing to launch /usr/lib64/
kdeinit4: Communication error with launcher. Exiting!
Communication error with KInit.
startkde: Could not start ksmserver. Check your installation.

Which is weird because:
> which ksmserver

I have this in my .vnc xstartup:
xrdb $HOME/.Xresources
xsetroot -solid grey
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &

I've read several related vnc threads. It appears to me I have a more general X11 setup failure, but at this point I'm lost.

Fedora :: Thunderbird Does Not Display Message Content+

Jul 31, 2010

I recently got the problem that Thunderbird does not displays the messages anymore. The e-mails are downloaded form the server, a new email warning is given, but the e-mail cannot be displayed (in fact it is not loaded in the message window. I could only see the TB start page). I cannot even see the old messages.

However, when use "see message source" I can see the e-mails.

I also noticed this message in the error console:

server does not support RFC 5746, see CVE-2009-3555

I use Fedora 12 + thunderbird 3.0.6-1

On another linux box F9+ThB 2.0.0 I do not have that issue.

Today I upgraded to Fedora 13 + TB 3.1.1. This should be the latest one, but I still cannot see the message.

Also, on F13 I got another issue with Firefox 3.6.7. When I switch between the tabs, the tabs will turn black and will not get back to normal for 10-15 sec. It looks liek a random effect because often only part fo the page turns black. This issue appear in the windows of TB 3.1.1 since updated to F13.

My hardware is a Sony SR49 laptop with ATI mobility Radeon HD3470

Have Google chrome and this black page issue is not present. The same with Evolution mail, but I do not like it.

Fedora :: Black Screen And Message - Cannot Display This Mode 2:dvi-d - During F11 Install

Sep 1, 2009

F9 has been running great since it came out. I read that one should install F10 before F11 so I did install F10! Everything went great.

(1) Then I tried to install the F11 iso dvd. After the "anaconda started" message at the bottom of a blue screen, the screen went blank and occasionally the message would appear: "cannot display this mode 2:dvi-d". Thinking the monitor had gone into power save, I hit many keys and moved the mouse to no avail.

I gave up! BTW I had checked all media CDs for errors.

(2) then working under F10, a little message appeared from the lower right of the screen asking if I wanted to upgrade to F11.

I accepted and again "cannot display this mode 2:dvi-d" on a black screen after anaconda started on a blue screen. This time no ISO DVD F11. I've never seen such an error message in 11 years (off and on) of using Linux. HD Disk activity was showing on the disk activity light so I let it run all night and part of today. I hit a bunch of keys and moved the mouse and the blue screen returned saying all was done and restarting.

After restart, I seem to have F11 installed. I did a yum update and got some more F11 updates. On the grub screen, the only F11 kernel was the PAE kernel which I selected
and got:

Does F11 have any F11 kernels? BTW running >setup (hd0,0) under F10 grub ruined my XP prof OS on scsi 0 so I reloaded XP Prof from scratch.


(1) what is this "cannot display this mode 2:dvi-d"?

(2) Now I cannot boot to Fedora 11 and all the advice on how to reinstall grub has failed failed. Did a rescue and chroot /mnt/sysimage and the fdisk -l

Now XP Prof seems to be on /dev/sdc and Fedora on /dev/sdd. What do I do? In the meantime I have retreated to Fedora 10.
