General :: Adjusting Screen Resolution On Ubuntu 10.10 Booted From Disk?
Dec 16, 2010
I just booted ubuntu from a disk that I burned to try and salvage some files off a hard drive with a failed boot sector (maybe. not sure what the problem is,). Anyway, I can see the files, and I have a large portable hard drive that I can use (a MyPassport 320gig, if I recall correctly). I'm having trouble accessing the drive, and I think it might be because there's something popping up in the task bar that I can't see. Unfortunately, I can't see the task bar! My screen's resolution is off, and I'm having trouble adjusting it. I browsed the various settings and I couldn't figure out any way to change it.
Is there anything I can do? EDIT: Oops! I didn't look into the Monitors options... how embarrassing.
EDIT2: Okay, looks like I can mess about with the resolutions, but all of them still deny me access to the full screen - still can't see the task bar.

The image on my external monitor is blurry. the resolution is right, but the Monitors menu shows the monitor to be a 20" while it is actually a 19". So this may be a hint. I would like to know how to adjust the monitor size (if possible). How can this be done? I am running 10.4 on a dell precision 4400, connecting with the monitor via VGA.

After installing Fedora 14, I can't seem to make my screen brightness go above the absolute minimum. I've tried editing /proc/acpi/video/VGA/LCD/brightness to change the current setting from 20 to 100, but I can't save it, even when logged in as su, it returns "Invalid Argument" when I try to enter the filename of where to save. What do I do?

Booted up system and it stated please insert system disk press any key.So it sounds like my startup got corrupted? I running centos 4.5 on it (old yes) Is there a repair I can perform by a disk? Would it matter if I chose i386 or x86? I cant remeber which version was installed on it.

I am running a dual boot conifg with OSX and Ubuntu PPC (karmic) on a 2004 G5 and everything is working pretty well - very well actually. The last thing I am trying to adjust is such a simple thing, but I just can't seem to get it. In Ubuntu, the screen position is shifted to the right, covering the scroll bar of windows and the trash can.
No problem, just use xvidtune, adjust the screen as I want and create a custom modeline right? Well, it does not seem to work.Here is what I did:Using xrandr I created a --newmode and then used --addmode to add it to the output I am using (default):
Code:
mieren@G5-Ubuntu:~$ xrandr --output default --newmode 1680x1050_new 146.25 1680 1820 1996 2268 1050 1053 1059 1089 -hsync +vsync
mieren@G5-Ubuntu:~$ xrandr -q
Screen 0: minimum 320 x 240, current 1680 x 1050, maximum 1680 x 1050
[code]....
Notice how the new mode now lacks the rest of the config information specified in the --newmode above, not sure if this is normal.I can change to the new mode, and the resolution is correct, but the screen is still not adjusted. There is no difference switching between the 1680x1050 and the 1680x1050_new modes - the screen may flash, but the position does not change.
(I also tried adding a mode line to /etc/X11/xorg.conf screen section, but it also has no effect. Actually, there was no xorg.conf existing at all, so I created a minimal one.)It is really annoying to have to adjust the screen position using the monitor controls on every reboot.

I recently switched my os to Ubuntu 10.04 Lucid Netbook Edition. After installing, I noticed that I am unable to adjust the brightness of my screen. The Fn keys do not work and I cannot find any other way to adjust it.The only way I have been able to adjust it is at the BIOS with Fn keys.

I 've just upgraded to Ubuntu 11.04 and I had a really hard time doing so. I have downloaded and burned the ISO, I restarted in order to install ubuntu and my computer booted from the disk drive, no problem so far.After I chose my language the purple screen with the option "Install Ubuntu" appeared and I highlighted the option and pressed "Enter". THEN, I got a black, empty screen while I was able to listen to my disk drive reading the disk.Everything was OK except for my screen.I thought there was a problem with the ISO or the disk itself. But, I 've tried different CDs and DVDs and I also downloaded the ISO several times. Unfortunately, I had always the same problem: disk drive working (making sound), screen-->BLACK-EMPTY. I was about to give up hope when I decided to turn on my desk lamp because it was getting dark. I was working on my last attempt and after I, once again, pressed "Enter" on the "Install Ubuntu" option I got the same dark screen as always but this time, because of the lamp, I saw that Ubuntu was actually being installed but the screen did not have any light. I managed to install it properly using my lamp to see what's going on on my screen but it's obvious that I can't possibly work that way. SO, how do I make my screen light come back so I can enjoy my new OS???
Note: My screen is working perfectly with windows so, it cannot be a hardware problem.

I'm using squeeze. I wanted to know how you could determine from the command line in tty1 (or tty2 through tty6) what the resolution was that text was being displayed at. Is there a way? I know that in grub, you're supposed to be able to go to the command line and type vbeinfo. I tried this and got some information, but somehow I think it doesn't always apply to the terminal after the computer has booted up.

My system decided to crash on me, hard. It was humming along happily for about 2 months and now doesn't boot. If I boot from hard-disk, I get grub. Launching the first kernel choice hangs. I thought maybe the install was corrupt, so I booted from usb install disk. The usb hdd didn't boot; something about an error trying to access /dev/sda . Unplugging the internal disk and plugging in the usb install disk does result in the system booting. Plugging in the internal disk in a running system usb-booted system does not result in the system detecting the disk.
How do I know if the disk is physically broken? This seems unlikely since it does manage to launch grub consistently. Or is this still possible? How can I try to mount whatever is left? The usb install disk doesn't even list the /dev/sd*. Any pointers on how to reformat the drive if it's not being mounted?

Unfortunately my experience in the Unix* based world up to this point has only been using web servers and administrating them, no GUI experience of any kind so I am completely unfamiliar with the setup and entire usage of Xorg or any other Window manager at this point. The issue I am having is with the screen resolutions I am being allowed to chose for my Dell Studio 1535 running Fedora Core 13 and the KDE 4 desktop GUI, thus my issue since I am not really familiar with how to run a Unix* based GUI in the first place.
The basic information, if there is more needed just advise what and what command gathers that info (or what conf/log I should look into in order to find it). Laptop is a Dell Studio 1535 Video is the Mobile Intel GMA X3100 ATI Radeon HD 3200 Graphics. LCD interface is the LVDS.
So far it seems to give me modes for 1024x768 and on down, nothing above this. I believe I am supposed to use the radeon driver being that is the type of card it is but every time I change the xorg.conf file to use this instead of vesa the system wont get past the loading screen anymore upon reboot and nor can I seem to find a way to bring up a command line so I can hit up the Xorg.0.log to see what is wrong or change the xorg.conf file back to the original driver it had listed.
I am going to assume this is a missing driver or something else it hangs on but without being able to get access back to the system and having to rebuild it again (re-install via live CD) I am basically out of luck at this time. Sorry for the rather poor post but I do hope to receive some basic directions on where to go from here with this issue

I have a Toshiba NB305 on which I've installed 10.04 and then 10.10. I set it up to dual boot windows, but windows has never booted. I get a quick blue screen, and then it goes back to the grub menu. Ubuntu boots just fine. I occasionally have reason to boot into Windows. So it would be nice to get it working. Here's the output from boot_info_script.

I just rebooted from an yum update, which updated my kernel 2.6.31-something to kernel 2.6.32-whatever-is-up-to-date-in-testing. My disk layout was LVM2+encrypted root. When I rebooted it prompted me for the encryption password as always. After I entered the correct password the loading screen (progress bar) finishes up as usual. Then, the screen is black.
It just stays in console resolution, but its just black. No typing, no chars, no X-mode, no errors, no VT-switches, nothing... just black. I remember to have started at 2.6.27-something and never had to kernel-update problems, so I dont know why it's annoying me now with todays update. I cant work with the machine any more.

I'd like a distribution with KDE.
I've tried Kubuntu, but I don't get any higher screen resolution than 640*480. The graphics adapter that seems to get me in trouble is an Intel based one.
I'm open to other OS'es that uses KDE -I just need to be able to use Kdenlive.

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.

Have just installed my frist linux os and the screen has a big black border around it. Set the res on install to 1024x768 & this is displayed in display settings.

i have been searching for the past few days on how to do this i have found many articles all telling me slightly different ways of doing so but none have worked. the monitor i am using displays at 1680x1050@60Hz however most access will be from a laptop running at 1366x768 through VNC i have the VNC working thats not a problem my current problem is that when i turn it on the screen defaults to 1600x1200@60Hz when i go to System>Preferences>Screen Resolution the options i get are 1600x1200, 1280x1200,1024x768, 800x600, 640x480 however when i change to something other than 1600x1200 the refresh rate changes to 85Hz and cannot be displayed by my monitor so i have to wait for it to default back, not that i want to change it to any of those in the long term /etc/X11/xorg.conf looks like this (i have only edited the Modes line)

I just installed 64 bit Debian 6 (Squeeze), and the O/S will not identify my monitor or allow me to set screen resolutions higher than 800 X 600.
I had the same problem in Debian 5, and remedied it by editing the xorg.conf file in the X11 folder in the /etc subdirectory. Worked like a charm.
Debian 6, however, has no such conf. file, and the Debian installation notes at Debian Wiki says Debian no longer uses Xorg as a video driver.
I am, therefore, completely lost.

I wonder if anyone can help, I've got an annoying problem with an Acer Revo running Ubuntu 9.10 with the latest NVidia drivers. The Revo is connected to my TV via an amp by HDMI. The Revo didn't seem to like this, I'm assuming due to some handshaking issue with the HDMI which meant that no signal was being passed. Therefore, in Xorg.conf I have used
Code:
Option"UseEDID" "False" This makes the a picture appear but the highest resolution available is 640x480 (if I connect directly to my TV and comment out the "UseEDID" line the resolution is the proper 1920x1080).I have tried editing xorg.conf (the file is posted at the bottom) to force 1920x1080 resolution but nothing seems to work.
Code:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 1.0 (buildd@palmer) Sun Feb 1 20:21:04 UTC 2009

On the boot up to the Grub loader screen my monitor (Acer X193w) displays a "screen resolution not supported" message in a floating window, even though the Grub screen itself is displayed. It appears as a flattened rectangle, like wide screen format films on a TV (black bar top and bottom), the floating message on top of it. Once Debian is selected and boots, obviously my xorg.conf takes over and sets the 1440X900 resolution and everything is fine. But the Grub start up bothers me. How do I set the resolution of the Grub loader screen?

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?
