Ubuntu :: Just Changed Graphics Resolution In STARTUP MANAGER - Black Screen
Jan 18, 2010
I just stupidly changed my graphics resolution in System - Preferences - Startup Manager, now i dont get a login window or anything just a black screen. I also disabled the splash but i assume this just gets rid of the ubuntu loading line thingy?
the weird thing is that the resolution was set to 640x800 or something like that in the Startup Manager as default and the laptop im using (an old Toshiba Amilo P4) supports 1024x768. the System - Preferences - Display menu wouldnt let me change any display settings which is why i was messing about here. I havent got any backed up x org file and only a live usb of super os/ubuntu - no cd or floppy drive.

I tried adjusting the resolution in Ubuntu so that it would fit better on my screen. The first one I tried worked ok, but when I tried a higher resolution the screen went black. Now I can't see anything on the screen so I can't change the resolution back to where it was. If I hit esc when booting up, is there anything I can do that will change it back to the default?

I downloaded some software yesterday from the ubuntu rep. This morning my screen has the bottom part of in black there are the KDE docky ,firefox ,terminal & rhythmbox icons ,so is the taskbar..but the wallpaper is cut up ,4cm off. I have noticed that the splash screens res has changed too. It's sharper (smaller). The browser as a consequence is also half lit & having noscript in the bottom without it being visible is a problem. Why has this happened & how can I fix it. The last working config, well that's somewhere else.

I've been using Ubuntu for about two years now, then suddenly today (after my PC accidently lost power) the screen resolution changed to 800x600 (it is, in fact, a widescreen monitor, and this resolution looked 'zoomed in'). The only two resolutions detected with xrandr were in the 4:3 ratio (800x600 and something worse). I followed some instructions, trying to reset the resolution to 1024x576.
I got as far as
$ xrandr --newmode "1024x576" ...
then,
$xrandr --addmode default 1024x576
but when I
$xrandr --output default --mode 1024x576
I a message to the effect of 'your screen can only support 800x600 or less'. Ah-ha, I thought, you stupid machine; this screen has had a greater resolution for over a year.
And so, from System->Preferences->Monitor, I forced the computer to switch to this new resolution. When prompted, I reset.
My current problem is that when I turn the computer on, the monitor displays a floating 'Input Not Supported' sign. I Ctrl+Alt+F1'd, and now all 'xrandr' and 'cvt' commands return:
Can't Open Display
My first priority is to get the computer back to it's less-broken 800x600 state;
EDIT: I'm running Ubuntu 10.04

A few minutes ago, I was connected to my remote machine running Ubuntu 10.10. I changed the resolution of the screen while connected with VNC, but now I can't connect to the remote machine. How can I fix this without leaving my house?

I changed may graphic card, earlier I used NVIDIA FX5500 with nvidia driver, now I was trying to use ATI Radeon 7500, but there are problems with graphic configuration. At first attempt server started but after I changed a screen resolution the monitor went blank. I restarted a computer but after the X server started immediately the monitor wnet blank. I found that for completely for me unknown reasons Xorg was trying to use an NVIDIA glx module with radeon driver. I removed this nvidia driver, I expected ubuntu would be able automatically to set up a proper configuration, but instead of ubuntu complained about a missing driver. I also tried manually to set up some basic config using Xorg -configure but after that the Xorg server was stuck.

I installed Xubuntu the other night (completely wiped machine) and started doing all the updates on it. After a couple of reboots, I changed from the proprietary drivers, to the regular nVidia drivers. After doing this, the startup logo is displayed at a really low resolution. Is there a simple fix to change this and use the nVidia drivers as well?

I was wanting to use StartUp-Manager to increase the resolution of the GRUB menu and the boot logo screen. Changing the resolution for the GRUB menu works fine. But the Ubuntu logo that should show up during the boot process is all scrambled across the screen. I tried multiple resolutions to fix it and none of them work. How do I restore everything back to their defaults? I tried putting the numbers all back to where they where when I first ran StartUp-Manager but that didn't fix it.

I'm trying to run 10.10 off a USB. On one computer with a nice discrete AMD graphics card, the thing boots fine. On a Dell Latitude e6510 with Intel HD Graphics (the one that comes with a Core i7) I get to the boot screen, the initial text crawl, and then the screen blanks.
Now, I can hear the standard Ubuntu start up noise about 20 seconds later so I know everything is running, just the video driver is not.
I can not do a CD install or anything off the hard drive, only the USB. I'm wondering if anyone knows some edit you can do at the boot menu (using tab) to revert to some graphics safe mode.

Ubuntu has been crashing on boot. I used a recovery mode kernal and went into failsafe mode, upon which point a msgbox told me to switch to low graphics. Then Ubuntu looked completely normal and functional with no problems. To me - an Ubuntu amateur, it seems like a driver problem and that running in failsafe mode will have its setbacks.

The last few days I have had to reboot my Ubuntu-workstation when the screen suddenly goes black. After some seconds I get a pop-up with the message:
Ubuntu is running in low-graphics mode
There is some buttons that tells me I can do different things (like reconfiguration ) but whatever I do I end up loosing all windows I worked in earlier. And having to reboot to get back full resolution. I have not found any way to reproduce this behavior. It has happened after being logged in for several days and sometimes just after boot and login when I'm starting an xterm and in all time intervals in between the output of:
sudo lshw -C display

Recently upgraded to 10.04 after countless problems w/ Karmic & already problems with Lucid! The screen sometimes suddenly goes black, then goes into low graphics mode, if I let it, thereby changing screen rez & unless I reboot, I am stuck in this mode. If I don't choose temporary low graphics mode, I must reboot. Many others seem to be experiencing the same problem yet have been offered no solution by the developers. So.

just installed 10.10 on my Sony Vaio F laptop. Here's my specs:Processor: Intel Core i7 720QM (1.6 GHz)Memory: 6 GB DDR3 (1333 MHZ)Graphics: NVIDIA GeForce 330M (1 GB VRAM)Hard Drive: 500 GB (7200 rpm)Native Resolution: 1920x1080I shrunk my Windows partition, installed Ubuntu on it's own partition with swap space, and mostly everything went fine. When I booted up, the resolution was set at something like 2048x1536, and it only displayed the top left corner of about 70% of the screen. When I changed to any other resolution, it looked really bad, and the whole screen still wasn't displayed.
Then something popped up telling me to install a driver for my graphics card, so I did, figuring it would fix the problem. When I booted and picked Ubuntu, I was stuck with a black screen. So I restarted and tried booting into safe mode. I got in, and it displayed the whole screen at 800x600. Still no luck in regular mode, however.

I'm running Ubuntu 10.10 on what used to be a windows vista. I bought me a new graphics card today so that I could run dual screen (GeForce210). I saw a guide at [URL] and I followed it.
I typed: sudo apt-get install nvidia-current
then I restarted my computer, once again as instructed I typed:
sudo nvidia-xconfig then logged out as instructed...
After I logged out the screen went black and I was not able to login. So I restarted my computer. Now when I turn on my computer I am getting this error and it's stopping at it.
fsck from util-linux-n/g 2.17.2
/dev/sda1: clean, 255658/294092280 files, 5031534/117616640 blocks

Starting GNUstep distributed object mapper: start-stop-daemon: unable to stat /usr/bin/gdomap/ (no such file or directory)
speech-dispatcher disabled: edit /etc/default/speech-dispatcher
*starting the winbind daemon winbind
It stops on this screen. I do not want to wipe it but I cannot get it started. I do have an external hard drive and at the moment I am using my Ubuntu disc to "try Ubuntu" I was going to try backing up everything I have but it will not let me access root because I am not logged on to that user, is there anything I can do to get pass this? I've called around and no one is willing to work on my computer since it is now running on Ubuntu 10.10

I just installed xubuntu-desktop on my Ubuntu 9.10 desktop, just to have the option of using xfce ( I did the same with Kubuntu - kde). I have noticed that the Xubuntu splash screen now comes up rather the the Ubuntu default splash screen.
I tried to use Start-Up Manager to changed back to Ubuntu but Xubuntu xsplash screen ( one with the fire flies ) still comes up. Is their any way to change this back to the Ubuntu Splash Screen without the Xubuntu screne coming up at all ??

When I start ubuntu I get a black screen, I can't do anything, this started when I installed the new driver for my graphics card. I don't know what to do. I have a i7 core (64-bit) and nvidia GTX 260 (twice).

What happened was, i used sticonfig to attempt to OC my graphics card, it all seemed to work well, then i put some stress on the card and got a 'black-ish' screen. No matter i though i will boot into text mode (How do you do it normally? The only reason i could was because i crashed my system and could choose recovery mode to then choose text based) and change it back to default and it will all be fine, woo... But apparently you need to be in X server for that command to take effect. ****...........
How do i get into text mode from booting up?
How can i fix this?!
I have tried looking in BIOS but there is nothing there. Have i just fried my card? (It was close to max settings - although only on full load for like 1 second) Could booting up normally, and just 'going in blind' work, like opening up terminal with a hotkey and just entering the command from there....

I use Intel HD Graphics and every time I run a game, it black-screens and I have to restart a thousand times before the game works and I can switch to windowed mode (restart once to do this).

00:00.0 Host bridge: Intel Corporation Core Processor DRAM Controller (rev 18)
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18)

00:1a.0 USB Controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 06) .....
I also use an HDMI cord (since computer has HDMI support) so this may be contributing to the problem. The same does not occur with my laptop, which runs Nvidia graphics and Ubuntu. I really want this to not happen so I can play my games instantly without restarting a million times. Some games have yet to work (AssaultCube mostly).

Recently my laptop running Ubuntu 10.10 has had an abrupt power shutoff (actually several times -- my battery has some problems).
Now when Ubuntu boots, I get the startup screen, but after a few seconds, the screen goes black. I can still boot from the live CD and in fact I am using my computer from the CD to write this post.
A few more details: When I press the power button while my computer is in this "blank" state, I get hard drive activity. Also, if I press "power", and then "enter", the machine actually shuts down.power

I recently started using Ubuntu 11.04. Everything works fine with my monitor directly connected to the computer. I get a default screen resoluton of 1680 x 1050, which is just fine.
However, when I connect the screen through a video splitter to be able to use a beamer, the screen resolution defaults to 1024x768. Moreover, Ubuntu then detects an unknown monitor and I cannot select a higher resolution.
I searched for modifications of xrandr en xorg.conf but I have to admit I don't understand what I've read. So my question remains: how can I force Ubuntu 11.04 to start with a screen resololution of 1680 x 1050 (without first connecting monitor only, that is).
I hereby add some information I retrieved with the screen connected without the splitter, so you can see what hardware is involved.
Code:
dirk@LaboFysica:~$ xrandr
Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 8192 x 8192
VGA1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 474mm x 296mm
1680x1050 60.0*+
1280x1024 75.0 60.0

I am running linuxmint . Trying to configure my start-up resolutions using the Startup Manager. But they only offer 4:3 resolutions. (My screen is a widescreen, 1600 by 900). So I could check the 1600 x 1200 option but that is not the correct resolution. And I get a reminder from my screen that the resolution is wrong.

HP laptop with Intel graphicsunning Slackware current with a 2.6.38.7-smp kernel.Booting with the "nomodeset" kernel parm works but X gets stuck with a 1024x768 resolution. When booting without, the screen goes black after a few pages scroll by, just at the point where the console switches to a higher resolution. Changing to a different console didn't help, so I blindly log on and type startx, and the screen comes back to life with KDE running at the higher 1366x768 resolution, I try a few apps, the webcam, suspend to RAM, resume, and everything is now working flawlessly so it doesn't look like an X issue.At this point I can change to another console (or exit KDE altogether) and the screen is back on at the higher resolution. Looking at the X log and some dmesg output makes it seem that starting X possibly replaces, reloads or unloads a driver? If this is the case, how can I prevent the conflicting driver from loading in the first place?Quote:
dmesg |grep drm
[ 11.481967] [drm] Initialized drm 1.1.0 20060810
[ 11.637941] [drm] MTRR allocation failed. Graphics performance may suffer.
