I recently upgraded to Ubuntu 10.4 and, although that installation seemed to work OK for awhile, I have recently encountered a strange problem. I have a dual-boot system with Win XP and two releases of Ubuntu, 10.4 and 9.10. I installed the latter recently only to be able to run some legacy software. I believe the problem occurred sometime around or after the installation of the 9.10 package. Note that the 10.4 install was a clean install on a newly formatted HD, and not a normal upgrade from 9.10, which I installed later separately. The Ubuntu installations are on their own HD. Win XP is installed on its own separate HD.
Here's the problem. I can boot OK up to and including the appearance of the Grub 2 menu, which displays fine. From the menu I can chose Ubuntu 9.10, Win XP or several kernels of 10.4. The 9.10 Ubuntu boots completely normally, as does Win XP--no problems or irregularities with either of those. When I select one of the 10.4 Ubuntu kernels, the strangeness begins, as follows:
1.) The menu disappears, there is a brief period of blank screen, and then a bizarre screen appears. It has a violet/magenta background. The word "Ubuntu" appears in large type, with a couple of lines of text below it. However, all of the type is unreadable. Instead of being normal characters, all the text characters are displayed as blocks of seemingly random multi-colored pixels! I can recognize that it is supposed to be text, but the letters are just a bunch of colored pixels. I can recognize the large Ubuntu word because of its shape. Also, the whole text display occurs twice on the screen, one on the left and one on the right. Both are displayed as colored pixels.
2.) The screen stays there, as if frozen, and does not continue with installation of the kernel. After some experimenting, I discovered that if I press Ctrl-Alt-Del (!), the installation continues as one would expect: I soon get the normal login screen, am able to login OK, and my desktop soon appears as usual.
3.) However, once in the desktop, if I try to invoke a console window by pressing Ctrl-Alt-F1-6, the console window appears, but the text on the screen is again rendered as little bunches of colored pixels, completely unreadable. I can, in fact, login at these screens, but the text remains colored pixels. I can escape back to a normal desktop by then pressing Ctrl-Alt-F7, and the desktop comes back completely normal. Interestingly, if I invoke a terminal from the main Applications/Accessories/Terminal menu, I get a normal terminal in a desktop window that is perfectly usable.
4.) If, from the boot menu, I choose the Ubuntu 9.10 choice, everything works fine and as expected, including the Ctrl-Alt-F1-6 console windows. This problem only occurs with the Ubuntu 10.4 menu options.
Since this problem only occurs with the Ubuntu 10.4 menu choices, my guess is that there is something askew in the display configuration of those specific choices. But, I've not discovered what to check for that configuration or how to correct it. I've checked out the /boot/grub/grub.cfg file, the /etc/grub.d number files, and /etc/default/grub, but can't find anything that seems to be the cause or the remedy.
i recently installed 10.04 after hearing from a colleague that it was highly recommended, however after install, all i get is a black screen with various colors pixels at the tope of the screen. I've been trying to find a resolution, but have nevertheless come up empty, i really need to info that is/was on my desktop (passwords & such).
I have an annoying text color problem. I don't know what to change to fix it. I have played around with System->Preferences->Appearance to no avail. Here is the problem: I am getting very light colored text so only the currently selected item is readable. The funny thing is that in Nautilus, Firefox, Chrome, Amarok, etc.. it's fine. It seems to be in only some programs in boxes with selectable line items, but also in the area that displays status updates in FileZilla. So I'm not sure how to pinpoint the problem.
I have done a bunch of searches on this but the terms seem to get tangled in the more popular search of "colouring the output of grep / awk". I am trying to find a way to grep/awk through the output of a command to find text of a specific colour. The command's output has a range of colours signifying too many different things to specify using text, with colour being the only form of grouping.
When I boot up F12, after I have decrypted the hard drives and after the services have started but before I get to the login screen my display flashes a series of interlaced lines across the screen. As far as i can tell theres no other problems with my computer, everything else seems to work fine. Its been there awhile now and its still there after a yum update. On first boot up of the day it shows white/gray lines (firstboot.jpg) [URL]. On subsequent shut down, boot ups it shows a blue, almost denim like display (shutdown.jpg) [URL]. Theres no problem if i just do a restart. Maybe related as well, last week some time my computer froze (opening large file, watching dvd and had firefox open, guess I ran out of memory?) So I did a reboot using the button on my computer, at the point where I usually get the coloured lines it instead showed a snapshot of my desktop just before it crashed. Though this happened after I first noticed the coloured lines.
I recently downloaded Ubuntu 9.1 and burned it to a CD. However, I can't seem to get it to boot. I got to the main menu and selected to run it directly from CD, and the Ubuntu symbol showed up saying it was loading things, but then the screen went black and nothing happened even if I waited over 15 minutes. During this time the HDD light was flashing every second or two, and I could see about three white pixels at the top most row of the screen.
I've been playing around with some themes recently, and a couple of the murrine themes have messed with my menu bars (this isn't ONLY occuring in firefox, but occurs in every window with a menu bar).Does anyone know how to remove the colored menu bar, and make it normal?
Even though the windows look pretty good, I would love to put them back to regular white. I don't know why they are black, or how to fix them. The picture should show what i mean.
I got the serious problem after update my opensuse 11.2, after update the message appeared and said restart my machine to updates take effect and after restart system doesn't boot GUI workspace it boot into text like space named "Emerald - Kernel 2.6.31.8.0.1 - desktop (tty1)".What can I do to boot my machine into GUI again?
In my .bashrc I have the following lines to turn on colors for grep and ls alias ls='ls --color=auto'export GREP_OPTIONS='--color=auto'.I've tried changing the alias to export LS_OPTIONS='--color=auto' but that doesn't work.Is there anyway to use an export instead of alias. And are there actually any benefits to one way over the other?
I'm using Kubuntu 9.10 and I have a problem with my screen. I use the nvidia driver downloaded from the website, installed manually as I always do. I wanted to update it, but when I press ctr-alt-F1 to go to the console to stop kdm, I cannot see the usual black screen, but only a very strange blinking screen with lines and colours, strange symbols like $ & %. This happens for every F1 until F6, then F7 luckily brings me again on the graphical desktop.
I tried to install the drivers from the "Hardware drivers" manager in Kubuntu, but nothing changed. I don't know if it's an issue related to the kernel or to the driver. But I don't know how to update it without F1 console, and however it's a serious issue because I cannot do anything in case of desktop failure. The kernel is the last officially released (I don't use the proposed repos), that is 2.6.31-19.
After I succesfully instaled ubuntu 10.04 server, I applied
export PC1="[e[36;1m]u@[e[31;1m]h:w$ [e[32m"
and my prompt was nice and colorfull. But, when I make logout and login, my prompt appears all green ([e[32m.) After restart, nevertheless, it looses color settings (of course) and appears plain white.
What should I do in order to keep my prompt color settings permanently?
I upgraded to Natty, some images appear in negative colours in Firefox, but not all. For example, photos on Facebook have negative colours, but not the thumbnail versions of the profile pictures do not. I have tried reinstalling Firefox in Synaptic to no avail. On another partition I have an installation of openSUSE 11.4 sharing the same /home (and therefore all Firefox settings etc), but no negative colours.
I notice the colored syntax and keywords in the terminal - the green, the blue etc? I did this in my machine a long time. Now I cannot trace back to how I did this. I need to do this in a new machine right now.
I am working with Linux red hat project for my school projects. I am in command prompt and I see different colored letters. I have words in green and words in blue. I think the blue words are directories and the green ones are files is this true.
In 10.04 on a Shuttle the screen position is a few pixels off. I fix this with xvidtune for the session. I also get a new modeline. I build a new xorg.conf file (go virtual terminal, stop gdm, Xorg -configure, etc) and move it to /etc/X11. I introduce the modeline in the monitor section and reboot (I could do a service gdm stop...). Guess what, my screen is still a few pixels off. The documentation clearly states that if there is an Xorg.conf, it will be used. So what gives?
This problem has existed since the xorg.conf file was dropped. It is just plain silly that one has to engage in a geeky treasure hunt to correct a few pixels. This adjustment should be present in the System/Preferences/Montors. This is why Linux does not make it with ordinary users, making (superficially) simple things difficult.
Is there a way to get colored output when using tab completion in a terminal? My colors are fine everywhere else so I know that I've enabled a color terminal successfully. Using bash in Ubuntu (10.10).
i have just installed skype for ubuntu beta version. when i put my mouse over icons it will bring up a text box but the words in it are very very light colored
I have a new installation of Karmic 9.10 up and running but for some reason my Nvida Quadro NVS 280 SD graphics card can not align my Sony SDM-HX73 monitor correctly. On the left I'm missing 10 or 15 pixels and on the right I have a thin black strip of unusable screen.
Eee PC 1005HA : Ubuntu 10.10 Netbook Remix, using Desktop Edition at login screen, using Awn in place of Unity: No clue what's causing this. Menu pixels freeze, remain on top of windows. Cursor floats over, but interacts with the actual active window. Can't move it. This has happened several times now, but usually only lasts a few minutes. At the time of this post, these pixels have been frozen for at least 20 minutes. Relogging fixes the problem, but logging out and in again every time this happens isn't really an option.
I bought a 25 foot dvi to hdmi cable to play movies from my computer on my plasma tv. Green pixels appear on about 20% of the plasma screen; some jump around others stay in one place. I have a nvidia GeForce 7600 GT card. The nvidia restricted drivers are installed. I also tried using a mythbuntu live cd and had the same problems. Is this a problem with a bad cable, bad driver, wrong setup, or something else? How can I get rid of the green pixels?
Having recently installed puppy linux (pup431) on my sony pcg-c1mah laptop with a monitor of 1280x600, I am absolutely in love with it. It is so fast and smooth. However, there is one problem, the screen position is shifted up vertically, off by a few pixels (30 maybe). This makes most of the application partially off the screen, which is really annoying. Previously, I was able to install xubuntu (8.04) on it without any problem. The screen was perfectly positioned. It was the speed reason I decided to go for puppy linux. If xubuntu was able to set the screen correctly, why puppy linux can not.
It's been a while since I did any kind of graphics programming, but I would like to start learning how to do graphics stuff in *nix. I started reading the GTK+ 2.0 Tutorial, but a) I've only been able to write a small "Hello World" program, and that tested my patience, and b) I'm not seeing anything which allows you to plot a pixel directly. Back before I migrated to Linux, I used the Windows GDI SetPixel() function for plotting pixels sequentially (this was for a small fractal generator). Mostly what I'm asking is if there's any kind of equivalent function in *nix graphics APIs? GTK+? Would I have to deal with SDL/OpenGL?
Regarding this task, I am able to print colored output in my putty sessions using tput or ASCI codes but whenever I tried to send that output through mail command to my outlook maillox, It always goes without colored. I need to produce those coloured output of the scripts as it is in mail.
I have a 30" LCD with 2560x1600 pixel resolution. I would like to make and play videos at this resolution, but software decode is too slow, and the GPU accelerated decode (VDPAU) maxes out at 2048 pixels. It might be possible to decode 2Kx2K and cut-and-paste and reorganize the rectangles to fill 2560x1600. But someday I plan on getting a 4K screen (4096x2160 pixels) and I would like to support that too. For that it seems two video streams decoded by two GPUs and exactly synchronized would work.
i just installed ubuntu studio and it seems to be working fine but i'm having an issue where the both the left and right side edges of my laptop monitor are unresponsive/unclickable for about two pixels all the way down. it's a minor issue that i could probably get used to, but it's particularly annoying when trying to use a scroll bar in firefox or any other window that when maximized would have it just against the right side of the screen. instead of simply swiping the cursor all the way to the right i have to stop just short of the edge in order to use the scroll bar/any other function.
