Ubuntu :: Wrong Monitor Resolution At Bootstrap
Sep 3, 2010
Sometimes, randomly, when turning on my Ubuntu laptop (HP 6730b, Ubuntu 10.04) I get a wrong monitor setting (much lower resolution than normal) and it is not possible to set it correctly because the menu buttons are wrongly placed and some are not present (probably there is not enough room for them) I have no other way than to restart the system to get the right resolution. Can someone tell me this inexplicable (to me) behaviour? Of course I didn't change anything in monitor settings...

I have problem with resolution (@gnom desktop). In Yast --> videocard & monitor is all right. There is correct resolution 1366x768 (WXGA). Also the videocard ( I don't have really one, only chipset "Intel Mobile GM45" ) is correct recognized. But Monitor isn't recognized, and I don't know which one I have (It's notebook from acer).
Nevertheless if I go direct in monitor preferences (at the bottom the monitor with a ruler symbol) the resolution is set to 800x600 and I can only change to 640x480. The monitor is as 15" recognized (I have 15.4", even a bit more broadly - 1366x768) and now I don't know what to do. All symbols, all programs, everything is huge! How is it possible to configure the correct one resolution?

I am new to Linux (Ubuntu 10.4 LTS on a Thinkpad T40), now just two days, and had everything working nicely. But since I wanted a better higher resolution I tried to set the monitor resolution to a higher value. After selecting a higher resolution first the screen went black and now it has a white background and is steady but has flickering areas. The system is still working. How can I go back to the resolution that was working?

On my Acer laptop wit ATI Xpress 1100 I have a native resolution of 1280 x 800, and Linux Mint 8 (of the Ubuntu family) offers that resolution without a problem. However, a few days ago I connected my laptop to my TV, and since then the correct resolution setting has been LOST. It doesn't appear anymore in the Display settings and so I had to choose a lesser resolution - I am now looking at a less sharp screen! How can I delete it? I hope that I don't need to reinstall...

I just upgrade to F14 from F10 on a dual montor setup. Firefox behaives differently on F14 than on F10.
On F10 it followed the mouse pointer's location and show up on the correct monitor
When maximized at close, it is always displayed on the left monitor. When not maximized at close it will open on the monitor where the mouse pointer is located.
About minimize/maximize Firefoxe before closing and it seems to work in some case, but not for me.

My Acer AspireOne netbook has a native resolution of 1024x600. Most times I start up, the image is 800x480 against the left edge, black bar on the right side, and a repeated image at the bottom. (I can attach a picture if needed.)I've been seeing this problem since Ubuntu 9.10, but it's more common recently with 10.10. If I keep shutting down and powering back on, eventually it will come up in 1024x600 as I desire. If that happens, then I avoid shutting down and only use Suspend instead. However, anytime I need to reboot (for updates, etc.) the 800x480 comes back.
The Acer logo / BIOS splash screen is also in 800x480, but I only see it switch back to 1024x600 after Ubuntu loads and is shut down. (Repeatedly clicking on/off/on/off never results in the resolution changing to 1024x600.) So, I'm still suspicious that Ubuntu is causing this (no hardware). WinXP used to be on this machine, and the problem was never seen.I don't think any proprietary drivers are needed (but I am still a Ubuntu noob.) When the problem is occurring, I see this result for xrandr:
Code:
swope@netbook:~$ xrandr
Screen 0: minimum 320 x 200, current 800 x 480, maximum 4096 x 4096
VGA1 disconnected (normal left inverted right x axis y axis)[code]....
I haven't been able to find xorg.conf ... but I've read that recent versions of Ubuntu create the content dynamically.Not sure what other details I should be including, at the risk of making this post too long.

i got a dell computer running ubuntu. it is equipped with an ATI radeon 5450, using a dell IN2010 1600x900 screen. when i installed ubuntu, the resolution was just fine. then i installed the ATI driver, and from that moment on, i have that strange behaviour: when i start ubuntu, the resolution seems set to 1440x900, but stretched to wide-screen mode, so the font is somehow blurry. when i turn the monitor off and then on again, everything is just fine.i have catalyst control center installed, and the resolution is set to 1600x900, but i still have the problem that i described.

every since I installed natty in march my refresh rate has been wrong this makes it where I can not see the boot screen, this was not a big problem until I installed the developmental version of ubuntu to test for bugs and I can not see the boot screen, I went to the page that tells how to change the rate but I get this error when I ran xrandr Failed to get size of gamma for output default. This showing my monitor as default it does not show a name, I manually set it up in x server and it shows the correct rate and the correct monitor, but not in monitor preferences.

I've got a HD screen: 1920x1080p. Grub (1.98 ) has the resolution: 800x600 and Plymouth also. It is irritating me that plymouth shows a very ugly purple splash screen in a very low resolution (800x600). How can I fix that? I've got an ATI Radeon HD 4670, and use the drivers from ATI...

I installed Ubuntu 11.04 about a week ago and everything has been fine except that Ubuntu thinks my monitor has a resolution of 1024x768, while the actual resolution is 1366x768. I can't set a higher resolution through the visual interface (my monitor is detected as "unknown") Are there commands I can issue through the terminal to sort this out?

I have no other gripes but one minor problem; After the boot, the KDE4 desktop starts with a resolution of 1152x864 instead of 1280x1024 selected at display settings. Strangely, it seems to activate the correct resolution instantly when I enter the display settings menu that shows the intended resolution (no need to apply anything). Going to the settings menu is a bit bothersome after every boot.

I've just upgraded from Debian Lenny to Squeeze. It didn't go as smoothly as I had hoped, one of the casualties being the proprietary nvidia driver I had previously installed. So I fixed that using the 'Debian way' rather than NVIDIA's installer, and that is now all fine. So far so good. However, when I boot up, pre starting X, my screen is a much lower resolution than it used to be (640x480, I think). Really chunky and ugly as it runs through the start up scripts. I assume that somewhere early in the startup scripts the nvidia driver is being loaded and set to a low resolution. Can someone advise me where this might be, and what to look for? Am I on the right track? I stress that this is before X is started. Once X has started the screen resolution is as I want.

setting a resolution that my monitor can't handle, and now I can't figure out how to get back to a setting that my monitor can handle. When I first made the bad setting, the screen went black except for an "Out of Range" message in the middle, and wouldn't let me see anything to put it back. I ended up going to a text screen with a <Ctrl-Alt-F1>, logging in as root, and rebooting. Now, I can use all of my other user IDs (root, KDE test, "email only," etc.) just fine, but if I log in to the one with the bad res. setting, it just blacks the screen and I have to reboot again. The xorg.conf file doesn't even have any options for setting resolutions any more, so there's no way to explicitly disallow the one I set, and "deleting" (renaming) xorg.conf didn't help.

on an older computer. I get as far as the screen that asks if I want to try or install and then I get a message saying the screen resolution is wrong and I need to reset. I even disabled the hard drive in bios and still get this message. computer was built to run xp and had ubuntu on it before. I tried to upgrade the nvidia driver and broke it.

I have a desktop with nvidia 9300 connected to a 37" LG hdtv lcd with a VGA analog cable. I'm using this machine as a media center. Up until now it had a windows XP and (besides the fact that it had windows) it work with the correct resolution - 1920x1080. I've installed Ubuntu (the latest available) after to many crashes during hd movies...
I installed the nvidia restricted drivers (the display is plain black otherwise) and my tv is being recognized as a CRT monitor. Guess it's because I'm using the vga connector instead of the dvi one. The problem is that the highest resolution it let me choose is 1024x768. I tried to mess around with the xorg.conf but i discovered it doesn't exist.

I have installed Debian Lenny with LXDE on a Dual USB 500Mhz iBook g3 the login screen appears displaying the screen using "800x600" pixels with the screen resolution at "1024x768" - so the login screen fills 2/3 of the LCD with black space to the right and the image repeating itself in the bottom 1/3 of the screen The "System Tools" > "Monitors Settings" only list one setting size of "800x600" and "Auto" After trying to search for answers I have tried editing the /etc/X11/xorg.conf file (after stopping gdm and rebooting afterwards)
# ... after these lines
Section "Screen"
Identifier "Default Screen"
[code]...
But nothing changes.
I have also tried [ dpkg-reconfigure xserver-xorg ] but there is no prompt for resolution

I'm running OpenSuSE 11.2 with an Nvidia GeForce 8200 on board graphics card and am running the drivers installed from the file NVIDIA-Linux-x86-190.53-pkg1.run which I obtained from the Nvidia web site. I also have this vga directive on the kernel line in /boot/grub/menu.lst vga=0x346 Yet, sometimes when the system starts up it will go into 640x480 mode instead of 1680x1050. If I shutdown and restart a few times it will eventually come up in the proper resolution.

I've been working my butt off all day now trying to get the nvidia drivers installed and then (the hard part) get dual screen to work properly with them installed. Finally I've gotten to the point where both of my screens are working perfect but now the login screen is on the second monitor instead of the first monitor for some reason I do not know.
Here's my xorg.conf:
Code:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 1.0 (buildd@crested) Sun Feb 1 20:25:37 UTC 2009
Section "ServerLayout"
Identifier "Default Layout"

I've got a dual monitor setup. The primary one is 1360*768 and the other is 1024*768. When I fullscreen a video on the web [URL] it fullscreens to the smaller (non-primary) monitor, but cuts some off the right hand side, as if it is fullscreening the right size to display on the bigger monitor, but instead does it on the smaller one. It happens with any web video, if I click the fullscreen button on the player, it moves it fullscreen to the other monitor.

one of them is a TV with an HDMI input. The login screen shows up on the tv, so if someone is watching a movie, I have to pause it to switch inputs and login. Other than that, everything is fine. How do I get the login screen to show up on the main monitor?

After upgrading to 11.04, I've been experiencing this weird issue with my monitor. Every time I reboot or turn the monitor on, the colors in Ubuntu are all wrong -- really green. If I go into my monitor's control panel and go to the "Input Color Format" setting and switch it from YPbPr to RGB things go back to normal.The problem is that I can't seem to save this setting. Every time the monitor is turned off it goes back to the wrong setting. I never had this issue before so it makes me think it may have something to do with the upgrade to Natty. The monitor is a Dell SP2208WFP and it's connected to my computer through an HDMI port. I use the Intel video driver.

I have 2 monitor on and Nvidia FX5200 set up as twinview
Monitor 1 is an old Sony CRT @ 1280x1024
Monitor 2 is a Visio HDTV @1920x1080
I have setup Monitor 1 to be the primary using nvidia-settings but the GDM login keeps sowing up in the second monitor ; before the HDTV I had a CRT TV @ 1024x768 and all was good. My theory is that GDM determines the center of the Screen (both monitors together) and then centers on that monitor. If this is true then how may I override this behavior and force the GDM login to show on my primary monitor?

I just installed drivers for this nVidia GPU from the website. Now, whenever I boot, the screen resolution goes to 1024x768 instead of 1280x800 like I want it to. I have to change the screen resolution every time I boot into Ubuntu.

I use 2 monitors under Ubuntu 9.10, but I have them set up in a unique way. The primary (CRT) faces me on my desk, but the other (widescreen LCD) is turned away from me, because I use it only to watch movies from my couch. My video card is an Nvidia GeForce 9800 GTX+, using the proprietary Nvidia driver package, with Xinerama turned on, so the desktop extends across both displays. Given that setup, is there any way to control which display applications open upon? Several apps have started opening on one display or the other, seemingly at random. Further, some apps start on the primary display, but open their subwindows on the secondary display. It's very annoying, because I can't see the second screen, so I can't drag the windows back to the primary desktop.
I would also like to have VLC Media Player (or any other app) always open on the secondary screen, on purpose. I almost never watch movies sitting at my desk, but rather from the couch. I placed a VLC launcher icon on the secondary screen, but when started it opens on the primary display. (If you're wondering how I can click on anything from my couch, I have a wireless mouse there in addition to the wired mouse at my desk. It's my "remote" since I don't have a TV. Xorg will quite happily support 2 or more mice simultaneously, I discovered.)

I have a laptop connected via HDMI port to different external displays throughout the day. I have configured the displays (Settings > Displays) to turn off the laptop display and set the external display as primary. However, this setting only takes effect after login. Thus, I am unable to see the login screen greeter on my external display because I close the laptop lid, so I am logging in blindly to a gray login screen background.
he issue I am facing is that when I start the laptop with an external display connected, the greeter only appears on the laptop display. The gray login screen background image spans both laptop and external displays and my mouse pointer appears on both displays, so I know both displays are detected and configured as dual displays. But, I am guessing, the laptop display is set as primary while the external as secondary.
I would like to know if there is a way to dynamically switch the greeter between the two displays, regardless of which one is set as primary and secondary. Or, is there a way to configure the system such that if there is an external display connected via HDMI, then it is set as primary, and if no external display is connected, then the laptop display is set as primary?
I have searched all over the net and this forum to no avail. I read a post which required copying the user's ~/.config/monitors.xml file over to /var/lib/gdm/.config/ but this caused my laptop monitor to be turned off at login even when there was no external display connected.
Hardware: Acer Aspire 8730G, Core 2 Duo T9900, 8GB RAM, Nvidia Geforce 9600M GT.
Software: Debian 8.4 Jessie, Gnome 3.14.1, Gallium 0.4 on NV96 (I am assuming this is the Nouveau driver)
Contents of the /etc/X11/xorg.conf file which I generated with the command "Xorg -configure" as root in console mode:
Code: Select allSection "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection
[Code] ...
I suppose I will continue to login without seeing the greeter on my external display.

I've borrowed a copy of 11.4 DVD install disc from someone at work, everything went fine install wise. Except Grub taking control, which I didn't ask it to, but easy fix with yast, problem is firstly my graphics resolution is wrong, but I'm trying to work that one out myself as it always seems to be happening with distros I use on my machine. The weird thing is my desktop blinks! Every 10secs or so the whole screen goes blank and then reappears? I thought it might be the wrong refresh rate, but that's at 60Hz which is correct, would it be the resolution problem?
My hardware:-
P4 2.8
1Gb ram
Geforce FX 5500
Dell 1703FP monitor
I was trying to running diagnostic's from Opensuse, but the blinking was getting on my nerves and I'm not familiar with a non Debian based OS......yet! I've got compiz and all running on the hardware in my Ubuntu install after editing the xorg.conf, could I simply copy that to my Opensuse install?
