Ubuntu :: 9.10 "root Device" - Grub Screen Was Flickering ("Auto Adjust In Progress" Came Up On The Monitor)
Apr 6, 2010
I'm currently triple-booting:- Vista
- Ubuntu 9.10
- Ubuntu 10.04 (beta)Everything was working fine up until a few days ago.
But then... The first problem I noticed was that the Grub screen was flickering ("Auto adjust in progress" came up on the monitor). It wasn't enough to make selecting an option impossible, it's just never done that before. The big problem, though, came when I tried to boot up Ubuntu 9.10 (which I've had on my computer for ages). The Ubuntu logo comes up, but then nothing happens for about a minute, followed by the following error message:
Gave up waiting for root device - Missing modules (cat /pro/modules; ls /dev) LERT! /dev/disk/byuuid/4f743ef0-7a38-481e-613e-ceee3a70ba14 does not exist. Dropping to shell! The only thing I can do then is physically reboot the computer. This happens if I try either Recovery Mode or using the previous kernal as well. Both Vista and Ubuntu 10.04 (beta) continue to work without problem.
I'm currently setting up a dell server with hardware raid 1 on sas 6r. i got 4 sas installed on the server and configured to raid 1 as stated below, array 1: slot 0 & 1
array 2: slot 2 & 3
during the installation, the installer detect the array 2 as sda and array 1 as sdb.. so i proceed with installation on array 2. after completed the installation, the first reboot lead me to a 'grub-rescue" prompt. by following the guide at url Mode, i've noticed that the boot folder has changed to (hd1,1), which i believe it has changed to sdb1. default root device shows that prefix=(hd0,1)/grub.
Recently i've installed 10.10 and have a problem with flickering screen on VGA. I have 64-bit release, ge force 210, nvidia propietary drivers and two monitors:
No matter which monitor is attached to VGA, it flickers randomly every couple of minutes. Sometimes it flickers when i use mouse or keyboard, but sometimes it flickers by itself.
The problem after couple installations (10.10 --> 10.04 --> 10.10 --> 10.04-3) is that system goes to "busybox" after complaining about missing root device. I already have come to conclusion that this problem could be solved by telling the system that the root device is at sda1. However, I'm not able to start grub (by pressing "ESC") at boot before problems start. I'm able to start live-cd and I tried to install "over" the old one (same partitions without format, same username). No luck.
And in the busybox /proc/modules is empty for example. And the grub has worked with previous installations.
just installed ubuntu 10.10 on my external usb hdd from my 8gb flash drive doing this on a laptop, my primary hdd (internal) is running windows (230gb of 250gb used) so i got an external hdd (2tb) and I decided to install ubuntu on it
I would like to exec a script whenever a user mount a device. The device could be an internal device (for example a partition on a second hard disk) or a removable one (for example a usb hard disk). The script must have sudo capabilities even if the user is not included in the admin group. Is it possible?
The specific question: I would like to add acl option to a device whenever it is mounted. I tried fstab but it's changing the behaviour of nautilus see:
[URL]... so I would like to create a script with the command
Code: sudo mount -o remount,acl /media/data and auto execute it any time data is mounted.
I just installed ubuntu 10.10 did a clean install, formatting the previous ones. Install completed successfully, rebooted, entered in GRUB, chose linux, linux starts the my screen goes black, there is no signal coming to my monitor, linux runs fine though i think because I hear the ubuntu login drum. I press ctrl+alt+F1, but can't get to console either, the screen is looking for input signal. Should note the I have a Palit NVdia 9600GT gpu because I saw that people with NVdia card sometimes have similar problems.
why both ubuntu and centos 5.4 will only give me 800x600 resolution on my monitor when opensolaris immediately gives me 1280x1024?The first time I tried ubuntu it gave me 1280x1024 and now will only make 800x600...This is a viewsonic VG930M Monitor..
I have a problem with my graphics (exactly this one: [URL] I've got an Intel 845G chipset and a LG Flatron F900P monitor.A friend of mine convinced me to try ubuntu and I installed the 10.10 version. Everything (except the monitor's resolution) works all right.
My computer is: IBM Net Vista 8305-21G Chipset: FRU PN 49P1599 (Intel 845G)
Researching this problem, I find very often this solution:
Code: echo -n 100 > /proc/acpi/video/VGA/LCD/brightness Unfortunately, I don't have that on my old PC: Quote: ls -F --group-directories-first /proc/acpi/ button/
I don't know if this has been asked already, but I cant seem to find it anywhere. I have a gateway, p 7915u with an nvidia 260gtx graphics card. im trying to install ubuntu 9.10 64-bit on it but the screen keeps flickering before I can even install it or try without change.
Whenever i close and then open the lid of my Compaq nc6220 laptop the screen will flicker when actions are made like moving the mouse, opening a program or typing. This is a known problem for the Intel 915 card and the solution is to disable the RANDR process. The thing is i cannot get to the service managaer and the RANDR doesnt come up in BUM which i installed. Does anyone know how to disable RANDR or any other solutions to this very annoying problem?
I had 10.10 installed and decided to chance it by upgrading to the Alpha release 11.04.Graphic card is ATI Sapphire X1550 I think (512MB).Apart from trying to get used to the buggy interface (to be expected from the alpha), the screen keeps blinking, goes black for a second every 30 seconds.
When I first boot up it gets to the checking sensors, then freezes and the screen flickers all the time. I have to do a hard shutdown then when I turn the computer back on everything works normally in fact the boot time is greatly reduced! And so far the system has worked fine after the 2nd boot.Anyone had anything similar?
I am using Natty and its favoring me with too much of screen and cpu overloading problems.After some usage with movies or browsing, it gets a distortion and whole horizontal lines appear on the screen like a 8BIT distorted Video game. The background actually runs good, since i tried playing mp3 and got the error after wards. After distortion, the windows start flicker and changing. Is there any way to stop this?Second thing,The cpu easily becomes full while mounting drives or surfing itself.
I downloaded the 9.10 from the Ubuntu website (not as torrent, but as direct download) and I burnt the ISO image in a CD. I intruduced the CD in the computer where I want to install Ubuntu and I rebooted it. Then the Ubuntu install-try menu appeared. I chose "try" and appeared a white ubuntu logo fading in and out, and then some text that was like the boot up of Ubuntu. In that point, the screen starts flickering every second, and when I push the power-off button of my computer it stops flickering and says something like "you pressed power off - please remove the CD and close the tray", and then the computer shuts down.
The same happens when I choose Install. At the point it appears a progress number (0%) of the file system, the screen starts flickering and the progress it seems it stops, or at less it's extremely slow.My computer it's a bit old but I think that's not the problem. It's a Pentium IV at 3'40Ghz, 1GB of RAM and what seems to have the problem, a Nvidia Quadro 256MB graphics card (I don't know the exact model but if you need it I can find it).
I did a fresh install of Ubuntu Studio 11.04 on a machine with Vista previously installed. The computer also came with a Personal Media Drive (movable harddisk) of 500GB. The only modification to the HW conf is that I recently added a harddisk of 2 TB that I wanted to install Ubuntu on. (I.e. in total 4 harddisks on the scsi slots)I ran the install cd that I burnt form the iso and I chose the option to manually partition the disks, and I only partitioned the new Harddisk. The installer chose to make some partitions: grub as the boot loader, one ext4 partition of 2 TB and 3.5 GB swap space (and some kb of waste space).
The install cd was readable and the tests that could be performed on the install cd itself and on memory terminated ok, and install seemed to have worked fine. It also discovered the Vista / ntfs partitions. I thought the install would work ok since I had made the new disk the 1st to boot in the HDD boot priority in BIOS setup.
When I rebooted after install I got a blank screen. I then tried with making the Vista HDD the 1st to boot in BIOS, and then I got the GRUB screen with two options for ubuntu two for mem tests and two for the Vista partitions.I found it strange that GRUB would take over, since the grub partition should be on the new lower prioritized HDD in the boot order.When I run the first Vista option everything works. Vista boots. However, when trying to get it to boot either of the ubuntu options I get a flickering screen, in the normal ubuntu boot a white one where the upper third of the screen is more steadily lit up whereas the lower 2/3 is flickering. When booting with failsafe option the color is red/pink instead, but with the same flickering.
I have windows installed through virtual Box now but i have some questions. When i make it full screen it goes full screen but Windows stays in the middle of the screen small and doesn't adjust to the full screen. Can you make windows completely take up the full screen Can i access folders on my ubuntu drive ? i have a file in downloads i want in windows but don't want to reinstall it
the screen flickering after installing opensuse 11.3? There are lines flickering on my screen horizontally. I have the Mobile Radeon HD 4200 graphics, ACER Aspire 4540 Laptop. I am currently using the default video driver rather than the proprietary driver.
I've just installed a fresh Ubuntu 9.10 (I'm using Windows 7), after completing the installation, may laptop rebooted but following the white icon of Ubuntu were the 2 lines "Ubuntu 9.10 computername tty1 ...etc" appears and I could not login due to flickering.
I just connected my LCD TV to my desktop and now I get two things happening which I didn't get when I used a proper monitor:
the screen scrolls down and sort of flickers every minute or so, plus: every few minutes it goes competely 'blank' i.e. reverts to the blue screen of my TV when there is no signal.
When attempting to boot into Ubuntu 10.04, the screen constantly flickers. It'll stay off for about 2-3 seconds, then come back on for <1 second. This constantly occurs. When reaching the main screen (I think), I attempt to move into a TTY terminal, but the flicker continues. I have attempted to reset the X Server, stop the X server, etc., issue remains. The monitor does not turn off during this flickering. I am able to type, obviously.
Here are my system specs: AMD Athlon 64 X2 Dual (6000+) 2.00 GB RAM ATI Radeon HD2600 XT (x2, Crossfire) HP w2207h 22" Monitor, connected via HDMI
I also have VGA inputs on the back of the monitor and can attempt to switch the input, but that requires me to dig through a box looking for a cable, so I figured I'd post this issue first.
i always had problem with my ATI card and Gnome GUI i decided to install Debian without any GUI at all. After login in CLI i used those commands:"apt-get update""apt-get install alsa-base xorg kdm kde gtl-qt-engine" .I decided to manually install KDE because i had no problem with it in Open SUSE. After that I restarted my pc and got flickering login screen, I'm unable to swith to console becasue after hitting ctrl-alt-F1 I'm getting black screen. I searched google but with no luck, and if there was some solution it required you to be logged in into GUI.
I've been trying to install Fedora 10 but the screen flickers about once every two seconds (not at set intervals though sometimes 5 seconds sometimes < 1 second).I've been searching around and all posts I've read about hh ave pointed to an nVidia driver bug which would make sense since I have an nVidia card but these were all posted back in summer of '08 so I'm not sure if it is still lingering.
I have a problem with the screen flickering on fedora 15 (and lots of other modern distros, eg: ubuntu 10.10 and 11.04 and opensuse 11.4) i think it is something to do with xorg.conf as older linux distros work fine so i added one using
but i still have a slight flicker. my monitor takes an input at 50-60Hz how do i set that up in the config file or is that not what is causing that? and can somebody recommend me a nice icon set for fedora
I need to add this somewhere Code: ModeLine "1440x900" 106.5 1440 1520 1672 1904 900 903 909 934 +hsync -vsync in the xorg.conf no idea where!
so i have been trying to install ubuntu for quite some time now and i have run into a bit of a roadblock.
I have tried to install 9.10 and it installs just fine (the GUI works just fine and everything seemingly goes ok), however when i go to boot it, i get to a flickering screen asking for my username and password (this is not the gnome login screen, it is just a blank black prompt asking for me to login). however, the flickering is inhibiting me from easily entering anything in from my keyboard. Thus, i cannot log in to fix the problem (i cannot enter my password because i dont know if the keys i am entering are being accepted or not). and recovery mode does the same thing.
This happens if i try installing it straight up, or if i install it inside windows. I have tried all kinds of boot options and install options (all that acpi crap) but none of it works.
i even tried installing some of my old copies of ubuntu (8.04), but when i do that the grub cannot load the linux kernel. I have also tried both the 64-bit and the 32-bit versions to no avail.
I am running an ASUS motherboard, AMD quad core x64, dual Nvidia geforce 8600's, 6 gigs of ram, and PLENTY of hard disk space.
I am not a noob to linux at all, but i have never encountered a problem like this and i have no clue how to fix it. Hell, i dont even know how to go about fixing it without logging in.
I've put a new hdd into my old comp to try it out, I am using a usb to try and install. When I install I get writing scrolling down the screen then it flicks to a black screen and just stays there. Am i doing it wrong?
I am not able to change to any tty at all. if i press ctr+alt+ f4 nothing happes if i then press f7 and return the screen turns totally black and my gui is only recoverable witrh restarting my displaymanger slim.also when i press ctrl+alt+del in aqwesome (windowmanager) the computer reboots immediatly, what makes me think that, however the terminal isn't properly "seperated" from the windowmanager.After restarting slim and login to awesome i 'am able to change properly to tty's and back to xserver. after reboot i am not able to change to tty's properly again.
