Ubuntu :: No Display With VNC?

Mar 1, 2011

I could use UltraVNCViewer from XP Pro and Server 2008 to control the Ubuntu 10.10 desktop. The computer has not been turned off, but when I log in with UltraVNC Viewer, all looks fine but no display. I have a black screen with the mouse cursor I can move with the mouse on the XP computer.

I can still access the mapped drives on the Ubuntu Desktop, there are no errors when connecting, but no display.

OpenSUSE :: 11.4 Gnome 2.3 Display - CRTC Error That The Display Is Over The Maximum - 1920x1920

Apr 16, 2011

I have a fresh install of OpenSUSE 11.4 64bit and I have installed the AMD Display drivers for my Radeon HD 5970. Everything seems to be working quite well. I have a multiple monitor setup (1280x1024 monitor and a 1920x1080 monitor).

I have my primary display set to 1920x1080, however when I try to enable the second display, I get a CRTC error that the display is over the maximum (1920x1920). If I enable both monitors at lower resolutions, there is no problem.

I have done a fair bit of reading and have been unable to determine where this maximum is set, or how to change it. I'd like to be able to run both monitors at their native resolutions.

Fedora :: System-config-display Just Ruined Display?

Jun 29, 2010

I did not have any /etc/X11/xorg.conf, so I read on these forums that system-config-display would create one for me. I ran system-config-display and it created an xorg.conf. But now my display is all messed up!! So, I deleted the xorg.conf and nothing changed. Why on earth would the display still be messed up if I deleted the file that was causing it?? Does system-config-display change somethign else?

General :: X11 Forwarding - Error: Can't Open Display: <ip Of Display>

Jun 28, 2011

I have the following scenario that doesn't seem to work normally. I have a windows 7 pc from which I am using putty to connect to my other linux servers (all running redhat 5 and 6). So here is the scenario that works and one that does not work. And I'm trying to figure out the one that does not work. Scenario that works:

From windows 7 (putty) I ssh into Linux_Server_1.
echo $DISPLAY
localhost:10.0

I run xclock and I see it pop up on my windows 7 pc. I am using xming on windows 7 to help me populate the display from linux to windows. One that does not work:

From windows 7 (putty) I ssh into Linux_Server_1. Then from Linux_Server_1 I ssh into Linux_Server_2.
echo $DISPLAY
<no output>

I try to setup $DISPLAY with localhost:10.0 or 0.0 or even my windows 7 pc ip address:0.0 ....etc Then when I try to run xclock I doesn't work.

I get these error messages: Error: Can't open display: <ip of display>

Also as a side note all our Linux servers are sitting on one subnet. My pc is sitting on another subnet. I use vpn to connect to the subnet where the servers sit from my pc.

Ubuntu Networking :: Set Display And Xhost: Unable To Open Display "XXX.XXX.X.XXX:0.0"

Jul 20, 2011

I have configured an instance in AWS EC2. I am trying to set the display back so I can run x apps. I login using ssh -xy -i...

export DISPLAY=XXX.XXX.X.XXX:0.0
echo $DISPLAY to verify
xhost +
xhost: unable to open display "XXX.XXX.X.XXX:0.0"

I have commented out nolisten tcp as suggested HERE I have modified /etc/gdm/custom.conf as suggested HERE Actually, the last suggested modifying /etc/gdm/gdm.conf, but that file didn't exist, so I added the line: DisallowTCP=false to /etc/gdm/custom.conf I rebooted, and still I get: xhost: unable to open display "XXX.XXX.X.XXX:0.0"

Programming :: HTML5 "details" Tag Display - Inline - Display - Hidden CSS Ignored - Firefox - Seamonkey

Jan 11, 2011

I'm testing HTML5 for the first time, using Firefox (beta) 4.0b8 and SeaMonkey (beta) 2.1b1, and its ignoring some CSS. Specifically, I have problems with the <details> tag. (It is nested in a paragraph...I am using it to provide an in-paragraph definition in hopes it can be toggled.)

Firefox only partly supports <details>. It's not supposed to show anything except the content of <summary>, unless you click on <summary>'s content. Instead, it puts a line break before the content of <details>, splitting the paragraph in two peices (which looks silly), without the "closed/open" functionality.

So I tried using "display:inline" in my CSS, but that gets ignored. Just for fun, I also tried "display:hidden" (also ignored) and "display:none" (obeyed).

SeaMonkey doesn't doesn't do anything special with the content of <display>...but it also ignores the same CSS as Firefox.

The only thing I can do to support semantic design is apply "font-style:italic" to all <details> elements.

Granted, you might ask, "why bother using <details> at all. then?" Well, I would like to have <details> for the browsers that support it, with the "font-style:italic" to degrade the page nicely for those that don't (such as for SeaMonkey).

Does anyone know why "display:inline" and "display:hidden" get ignored?

Ubuntu :: Will Not Display - No Signal

Jan 16, 2010

When I start Ubuntu, the Ubuntu logo appears, then the screen goes black and "No Signal" appears on the monitor screen.

Earlier today, I installed a new processor, a dual-channel AMD from a single channel AMD. I decided to put the entire computer into a new case since I was dismantling everything. I have two hard drives: one for Ubuntu and one for Windows XP.

When I started it up, I got errors 13 and 17. I went into the BIOS and changed the disk order. Now Grub appears and I can get into Windows, but I cannot get into Ubuntu.

Ubuntu :: Location Of X Display

Apr 20, 2010

On Ubuntu (as with 99% of other Linux distros), CTRL-ALT-F7 brings you to your X display on tty7 (:0)...is there any way for me to get the display to appear on tty2 or tty3 instead of 7?

I ask because my ubuntu box is a media server running XBMC. XBMC has some 'flaws'...one of which is screen refreshing during certain tasks (other than watching a video)...the easiest way to get it to kick back into gear is to switch to a terminal, then back to the X display...not that big of a deal really..but the problem lies in the fact that the remote I use for the computer (simple USB IR Remote grabbed off of eBay) has buttons programmed for CTRL-ALT-F[1,2,3,4]. So, if I could get X to appear in CTRL-ALT-F2 for instance, I could easily switch back and forth without having to get up to walk to the keyboard.

Ubuntu :: Display Going To Sleep?

May 14, 2010

How can I stop my display going to sleep?

I've got the Power Management settings for mains power as:

Actions - put computer to sleep when inactive - never

Display - put display to sleep when inactive - never

Screensaver settings are:

Regard computer as idle set to 2 hours

Unticked Activate screensaver when computer is idle

Yet the screen still goes blank after a few minutes when I'm not using it.

I dual boot and it doesn't do it in Windows. It didn't do it in 8.10 or 7.10 either.

Ubuntu :: Display Progress Bar Using Cp (if Possible Mv Also)

May 16, 2010

A quick google search gave me a possible answer at this post: [URL] However, this isn't my question exactly. It sort of is, but the answer is not correct for me. I'm wondering how to show progress of a cp or mv command. The man page says -v should do it, but it seems it doesn't show any progress at all. Is it possible to show progress info with cp or mv? Or, is there a different command I could use that would show a progress bar. I know for example scp will show a progress bar, but that is for local-->remote or visa versa, but I'm trying to copy locally.

Ubuntu :: 10.04 - Only Have 2 Display Modes

Jun 24, 2010

Just installed Ubuntu 10.04 via Wubi on my laptop. It's looking good so far but to cut to the chase, I only have 2 display modes. This is 640x480 and 800x600. Is there anyway to 'trick' the system into getting a 1200x800 display mode as I have found that graphic drivers for the SIS Mirage 3 are non-existent.

Ubuntu :: No Display During Boot?

May 4, 2011

I'm quite familiar with CentOS and have used ubuntu in the past, recently I decided to do a clean Ubuntu install and I've been running happily for about a week. That is until I decided to upgrade from 10.10 to 11.4.

The first thing I've noticed since upgrading is that I can't see any part of the boot process as the screen just displays "Out of Range" until I'm shown the login screen, no boot selection and no display of drivers being loaded - which can cause problems when you need to troubleshoot. No worries I thought....

However, I noticed that since the upgrade moving windows around on the desktop was slow which is probably because I'm not using the right driver, so I decided to let it install the recommended driver.

Now I never see the login screen. It just keeps saying "out of range" for eternity. I've even tried booting into runlevel 1 - still the same thing. Do the drivers actually apply here?

I've also renamed my xorg.conf in an attempt to fix things - no luck.

Is there a way to get back from this without a reinstall?

Ubuntu :: No Display On Different Monitor?

Aug 10, 2010

I successfully installed linux mint 9 and at the same time update the system. Now that everything is running, I returned the pc to the owner, but when I power it on, no display. You can see the post but no display after that. And 1 more, I press the shift while loading grub2, nope nothing happens. And also tried booting the CD installer, same results.

I installed the system using an old 15" CRT monitor and the owner had a AOC 1619sw LCD monitor. I found this thread from ubuntu which I think was the same problem as mine, [ubuntu] Help! No display/keyboard on boot with differnet monitor - Ubuntu Forums, but no solutions yet.
