Ubuntu Multimedia :: Monitor Display Is Messed Up After "waking" Up?
Feb 24, 2011
I'm running ubuntu lucid on a home-built computer with an ATI Radeon R300 NE [Radeon 9500 pro] video card and a cheap-o (Norcent) flat panel. Within the last week I've had a problem where the display gets horizontal and vertical stripes when I "wake it up" with the mouse. I can almost see what is supposed to be on the screen and I can use the mouse (the cursor is a big blocky area) enough to shut the computer down. Oddly, opening a new terminal (TTY1?) using Ctrl-Shift-F1 doesn't fix the monitor problem. Also, you can see the display problem when using xvnc4viewer from another computer.
I have found a number of similar issues in the forums, but haven't found a solution (nor can I find xorg.conf in lucid...). It just happened, so I wonder if it is something that broke in an update. There is nothing recorded in the logs that seem to apply to video problems.

I have to hold a presentation using a projector in a few days and I have to bring my own laptop, so I tried hooking up a second monitor to test if it works. As it turns out, the second monitor works fine, but then my main screen is messed up. I'm using Ubuntu 9.04 and I'm doing this on a HP Pavilion DV4000 laptop. My main screen shows just the bottom (cca) 400 pixels of the wallpaper, no bottom panel, no desktop icons. And I'm kind of scared to remove the second monitor now cause I don't know what I'll do if I don't get the main screen back.. Well, other than installing 9.10 beta that is..

How could xorg be set-up such that different monitors work with different DPI but still compose the same extended display?
I have a 15 inch laptop display extending to the right the main display which is 23 inch. The resolutions are comparable, but the difference in pixel size is very large. Thus, either the external display has too large fonts and UI, or the laptop one has them very small. Moving them at different distances is not entirely possible.
xrandr info:
eDP1 connected primary 1920x1080+2048+0 (normal left inverted right x axis y axis) 344mm x 194mm
VGA1 connected 2048x1152+0+0 (normal left inverted right x axis y axis) 510mm x 287mm
I heard that Windows has a hack (which I can't check) for extending displays with different pixels sizes: it computes in which of the displays a window has most of it's surface and sets the DPI for that window based on that. Thus a window will change DPI when crossing monitors, (and will look too small/large on one of the monitors if it is in the middle).

All of a sudden today there was no display on my Ubuntu PC. It seems to be powering on - I get the LG screen when the monitor is switched on - but it goes into "Power Saving Mode". How do I diagnose this? I already unplugged and plugged. Monitor is connected to a graphics card - no change when I switched to VGA.

I have an ASUS 1000HE laptop running Lucid 10.04 (Desktop not netbook version) which I have connected to an external display (LCD). I don't intend to use the laptop by itself anymore therefore I have configured the display properties to turn off the laptop display and use the external display as primary. However, when the PC enters 'locked mode' or the display powers down after a defined period of time (as set in the properties) when I wake the PC and the display, it turns the laptop monitor back on .... switches the laptop screen to primary display (i.e. with the panels etc displayed on it) and extends the desktop to the external display! The only thing I can then do is go back into the configuration utility and turn the laptop monitor off again and boom, everything is fine and dandy displaying on the external display again! I don't really want to have to do this every time I come back to the PC after it has been locked nor do I want to write a script (if it can be avoided) to deal with it!

I have a Radeon HD 5830, running 3 monitors on 10.10 64bit with the 10.6 video driver. The three monitors ( from left to right ) :
DFP1 : 1152x2048
DFP2 : 1920x1200
CRT1 : 1360x768
The problem I'm having is getting the middle monitor to be the primary one.
Running
xrandr --output DFP2 --primary
puts the panel on the middle screen but my docky and icons stay on the left screen. Flash videos also open up on the portrait left monitor which looks awful. Ideally I would like the icons on DFP1, docky on P2 and flash videos to open on P2. But I would definitely settle for everyone to be on the middle screen and drag it around as I please.

I asked this question in the installation forum and got as far as possible with the advice there. I'm using a 32" Insignia TV as my sole monitor. I'm using the HDMI from the integrated video on my ASUS E35M1-M motherboard. I have it running at 1920x1080. When it boots up the monitor says the BIOS is running at 1080p, but as soon as Ubuntu loads the TV switches to 1080i. When I was setting the computer up the other day it was running 1024x768 and the text looked beautiful, now similar size text is blue/black and scraggly/shadowy looking. I followed some instructions for xrandr, but ran into problems and the person giving me advice admitted he was too unfamiliar with xrandr to get me any further. Here's as far as I get:
Code:
erik@erik-System-Product-Name-System-Product-Name:~$ cvt -r 1920 1080 60
# 1920x1080 59.93 Hz (CVT 2.07M9-R) hsync: 66.59 kHz; pclk: 138.50 MHz
Modeline "1920x1080R" 138.50 1920 1968 2000 2080 1080 1083 1088 1111 +hsync -vsync
erik@erik-System-Product-Name-System-Product-Name:~$ xrandr --newmode "1920x1080R" 138.50 1920 1968 2000 2080 1080 1083 1088 1111 +hsync -vsync

My brother has just installed 9.10 on his Inspiron 6400 and would like to have a dual screen setup using both the laptop display and a flatscreen attached to the VGA socket. Using the standard display options, the two displays are recognised and when the 'mirror screens' option is disabled then settings applied it works to the extent of allowing the cursor to move between the two monitors; however the monitors display nothing except a black screen and the cursor.
I've updated everything to the current version, had a look for restricted drivers (none are suggested by the GUI tool thing) and checked both displays work (both independently and as mirrored). I also had a look for an xorg.conf to poke around in but there wasn't one there.

i recently installed the game warsow from the repository but the game used to close midway while loading and my dislay would get messed up(i have attached before and after screenshots). I would usually logout and login again, and the display would go back to normal.
But last time, when the display got messed up again, i ran `metacity --replace` in the terminal and now i am permenantly stuck with the messed up window. the desktop in other user accounts are working fine. can anyone tell me how to set the desktop back to how it was??

I recently tried to plug my laptop to a TV and adjusted the settings consequently. The thing is now that I want to use it with the laptop screen. I can barely see the first top inch... I'm pretty shure it has something to do with the display configuration since it works flawlessly when I log in as a guestIs there a way for me to reset the screen to it default config without using my regular session?

I have this weird problem; When I change the monitor preferences in the 'System > Preferences > Monitors' dialog, the colors and fonts of much of the text on the screen get messed up. The issue is best seen in the attached figure. All applications seems to run as normal, and there is no other trouble than the visual.
It happens in the moment i hit apply. It happens every single time. The desired changes is applied as they should. To turn my PC back to normal I have to restart it, and then it will start again with the new settings without any problems at all.
The problem occurred for the first time yesterday. I think it may have to do with some updates (advised updates through Update Manager) I have done lately (I tend to mindlessly install most updates). Other than that I have no idea what is causing the problem.
Have anybody experienced a similar problem? Does anybody have a clue of what is causing it, and what I can do to solve the problem? PS: I am running Ubuntu 10.10 32bit on a 5 year old Dell Inspiron 630m.

I'm running F11 with an ATI HD3850 graphics card. I donloaded latest version of the ATI driver and installed it (without paying to much attention to versions and pre-reqs). This caused my display to be unusable in Gnome, nothing can be made out of it.
Was hoping to be able to repair this if I atleast had a bash prompt, but when I press ctrl-alt-F6 (or any F-button) my computer restarts. how I could fix this without reinstalling?

I installed Karmic on an older PC I had laying around, and the only trouble I am having is with screen resolution. It uses an old ATI chipset (onboard) for video, and it doesn't seem to do EDID correctly, so I can't display anything higher than 800x600. I have tried creating an xorg.conf, but it's still not working. How can I tell Xorg to ignore the fact it can't detect a widescreen monitor and display something larger than 800x600? I noticed the log says the sync's are out of range, but I am not sure how to fix it.
Here is my current xorg.conf.
Code:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection
[Code]....

I have a bit of a problem w/ the windowing UI when I drag any window left, the display gets messed up (see attached screen shot). It doesn't matter what the program is, even happens in explorer. I've done some searching of the Internetz and this form and all I could find was this bug, that doesn't have any updates on it:
Does anyone know of a fix for this? I can make the lines go away by triggoring a repaint (by either dragging another window on top of this one or minimizing and maximizing the problem window, but it's still a bit annoying.I'm running Fedora 14 and have ran all of the updates it prompted me to run.

I am facing problem with the fresh installation of Fedora 11. (I have moved from Fedora 9). When I try to view videos on ..... or use the Cheese Webcam Booth, I get blurred lines on the screen and I am unable to see any video or pic.
Also I noticed that the when i go to System > Preferences>Display, it shows me UNKOWN MONIOR.
However, if I got to System>Administration>Display and enter the su password, it shows me correct monitor and the graphics driver.
I am not sure if my original is related to the Unknown Monitor.
I also tried to install Nvidia driver but it crashed the xserver and I had remove the driver.
My Monitor is LG 700E and Graphics card is from intel. as I am not able watch any video.

I am running Debian 8 with the Xfce Desktop Environment.
I was unhappy with the lock screen on Xfce so I removed xscreensaver and wrote a short custom locking script, which basically involves using i3lock along with some additional commands to make things pretty. I was able to change the default locking behaviour by modifying /usr/bin/xflock4 to run my_lock.sh.
Unfortunately, no lock screen appears whenever I suspend ie after waking the computer from suspension I don't need to type a password in. I would like to force Xfce to lock the screen with my_lock.sh before actually suspending, but I don't know how to do this.
I know that Xfce runs Code: Select allxfce4-session-logout -s when suspending, but xfce4-session-logout is a binary file which I cannot edit.

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.

Currently I have two 1920x1080 screens running in Twinview on my Geforce 275 graphics card. Want I want to do is a quick simple way of disabling my secondary monitor when playing video games or using xbmc to watch movies, etc. I've tried a few applets but they require the xandr function which I think Nvidia doesn't support.
Is there a way to disable this quickly other than loading up nvidia-settings and disabling the monitor everytime. I don't really want to use two seperate x sessions and xinerama due to the fact you can't use compositing.

I'm having some strange problems with my monitor. It's an LG Flatron L1730S and the graphics card is a Nvidia Geforce 5600FX. The monitor is listed as unknown in monitor settings and is going at 51 HZ with performance and out of range issues in some game. How can I get ubuntu to recognise it, or better yet change the driver?I did some googling and discovered a tool called displayconfig-gtk, but I can't install it in Ubuntu 10.04

every time I reboot and play a video file the colours are messed up. I need to manually increase then decrease the hue or saturation to get the picture to normal in smplayer. The colours aren't competely inversed as in the common bug with the totem sliders, they're just far too red and bright.Smplayer is the latest from PPA. I've checked the totem settings and everything is OK. It only takes two key presses to resolve but it's a pain, to be honest, so if anyone knows what causes this and how to fix it permanently I'd be much obliged.

system update today which moved the nvidia drivers from 195 to 260.After performing the update with synaptic and restarting, I noticed that my desktop theme, "Clearlooks," was messed up in that the shiny progress band was now two separate colours (blue and white). Tried other themes (among them "Glossy") and found most of them corrupted with, for example, the progress bar totally white.Similar problem with Iceweasel 4: the tabs have lost their inferior border, and the address/search bars are surrounded by white.I suspect (though I can't be sure) that the above is caused by the nvidia update. I did an "nvidia-xconfig" to try and see if this would change things, but no.

I have a Dell monitor attached to a Dell laptop. I am using Ubuntu 10.04 x64.
Spec:
Latitude E6500 : Intel Core 2 Duo P8800(2.66GHz,1066MHz,3MB)
Base Options : 256MB Nvidia Quadro NVS 160M Graphic Card 1 S
Display : 15.4in Widescreen WUXGA (1920X1200) 2CCFL
Dell 2001FP (attached using DVI)
When I try to boot into Ubuntu with the monitor attached I get a DVI: Cannot Display this Mode message on my monitor. I can boot into Ubuntu just fine if I detach the monitor. Have tried with VGA, but to no avail. I have the latest and greatest Nvidia drivers downloaded from the Nvidia web site. Googling indicates that this is a Dell problem, however, I am not sure about this. It worked just fine on my previous laptop (IBM T61) and Ubuntu 9.10, so I guess it has to do with the laptop and not Ubuntu 10.04.

I run Ubuntu on a MacBook Pro with an external monitor connected. But currently the external monitor only works with one user account. The External gets no signal and the laptop display is used on the login page. Is there any way of having the login page and possibly startup displayed on the external at all times for all accounts.
System > preferences > Display Doesn't work for me, I use NVIDIA X Server Settings

If I turn off the monitors, I get a black screen (the monitors goes to power save) when I turn them on again.
I have a workaround which involves pressing ctrl-alt and f3 and then ctrl-alt f7. That usually works and brings up the graphical login-screen. And I get my session back.
But sometimes when I log in, my session is gone. It is as if I was logged out or the system has rebooted.
I have two monitors and Nvidia.

I have a Visio TV that I dropped and cracked the LCD display in one corner, for watching TV it's basically useless now. On a whim I plugged it into one of my computers and about 75% of the screen is still usable. Only the bottom right hand corner of the screen is messed up. What I'd like to do if possible is to define an area of the screen. Say for instance the top left hand corner across and down to where the screen starts getting bad.
Like a left click and drag out the good area and then make only that area "the monitor" for the OS to use. I'd then probably build a case or something to house it in and only show the "live" area to clean things up. I'd like to use Ubuntu. But if you know I can't do it in Linux but can in Windows I'd consider that option as well. I just hate to junk the TV if I can use it some how as a monitor.

I'm running 10.04 as a DVR (mythtv). If the computer boots with the TV off it won't detect the settings, and when I turn the TV on nothing displays. I have to ssh into the computer and reboot it to get it to detect the display.Any idea how I can go about solving this? How can I disable autodetect and force it to use a specific setting?

Looking for a newb-type step by step process for configuring ubuntu to 1) recognize both the onboard video card as well as the PCI graphics card and 2) how to set up three displays with separate desktops (able to mouse-over from screen to screen). So far the 20+ hours searching online has yielded excessively complex instructions, inappropriate instructions, or ancient posts. Is this config even possible? Again, I am learning so the instructions need to be very deliberate. PNY GeForce FX 5200 PCI 256 MB 2 Port VGA + S-Video Graphics Card VCGFX522PEB and an onboard display apdapter (Intel P4 Chipset 845GV).

I have recently installed ubuntu using wubi on a dimension 9100 PC.When i boot up ubuntu I get a message that it cannot display current video mode when the GUI tries to launch. The monitor is a Dell E173FPb.From digging about on google it seems I need to edit the xorg.conf file? However, it doesn't exist in the /etc/X11 directory. Does wubi not create this file?
I then created a template of this xorg.conf with the "sudo X -configure" command. I then copied the created file to /etc/X11/xorg.conf and editied the Monitor settings. however, I still get the same error even when I put in the HorizSync and VerRefresh settings shown on the Dell webpage (31-80 and 56-76 respectively).
