I am not sure if this is really a Ubuntu question but lets try it!Received email shows a long header which includes lines of code. I can scroll through it but I can't reduce the number of lines on screen.This significantly reduces the number of lines available for the message. There must be a way to reduce or eliminate this header.
View 2 RepliesI tried to check how many workspaces my desktop could have at once, and it got stuck at 36. Now i can't reduce the number. When I click the workspace switcher, and press "preferences", the preferences screen flickers like crazy, and I can't change it. The window title bars and borders are altso gone, but gnome is running. I don't have compiz running.
Is there any way of reducing the amount of workspaces, through gconf, or terminal?
I have been experiencing a problem where the screen loads and after initial first few lines breaks up into multiple repetitions of lines. Reloading helps but has to be repeated when pageing down. Mail is no problem; it is supplied by my network provider. OS is openSUSE 11.2 which I update when advised. Below is a sample from the error console:

I recently found myself in possession of a large file (a few million lines in length) of short strings and would like to count the number of lines that are unique to the file. I thought this would be an easy process, but while working on the problem, I encountered the following. Can anyone explain this weird result to me?
Code:
alaric@alaric-laptop:~/Documents/Programming$ grep '^string$' file.txt | uniq | wc -l

I have a rack of four 1TB drives all partitioned identically with three primary partitions. On each drive
- the first partition is only 64MB;
- the second is a large 900GB partition and
- the last holds all the remaining space
mdadm has been used to set up
/dev/md0 - RAID1, comprised of /dev/sda1 and /dev/sdb1
/dev/md1 - RAID5, comprised of /dev/sda2, /dev/sdb2, /dev/sdc2, /dev/sdd2
/dev/md2 - RAID5, comprised of /dev/sda3, /dev/sdb3, /dev/sdc3, /dev/sdd3
OK, so it was a silly mistake to make - but I am now need to increase the size of /dev/md0. My thinking is to reduce the size of md1 so that I can grow md0.
On md1 I have two logical volumes. I've successfully reduced the size of the volume so that I can reduce the size of md1. Now I'm at the nervous stage; I can find little written on the topic of shrinking RAID5 arrays - and even if I do this I'm unsure if I can move partitions around to regain the space I so desire.
I have a netbook with LED backlight, but even the lowest brightness of the screen is still very bright and eye straining in a dark environment. On Windows and MacOSX there are simple tools that put a borderless more or less transparent black window in front of everything on the screen to reduce brightness even further.Are there such tools for Ubuntu or other means of achieving the same result?
View 4 Replies View RelatedCan the size of the Ubuntu desktop window be reduced so that it displays on a monitor or via a data projector with a surrounding black border? If so, how? The tragicomic chain of events which leads to the question is as follows. Community group, short of cash, want to equip lecture room. Pull-down screen is set up permanently on one wall. Contractor sets up old data projector via ceiling mount. Data projector is just too far away from wall, such that image cannot be reduced sufficiently by the data projector to fit on the screen.
Annoyingly the image, as displayed, is only slightly too large - just enough to lose the top and bottom panels, Applications menu, File Menu on full-size windows, Indicator applet, Trash, and restore desktop button. The data projector is hooked up via VGA cable to a recycled PC running Ubuntu 10.04 with proprietary NVidia driver (version 173) for GeForce 8400 GS. I'll give anything to be able to do this on the PC, rather than having to move the projector!
I keep hearing about how Ubuntu is supposed to be so much faster than Windows 7, but have yet to see any major difference in their boot times. I am dual-booting Windows 7 and Ubuntu 10.04 on an intel Centrino 2 processor with 4Gb of ram and both OS's take about the same time to boot. After I get to the bootmanager to select OS, if I click on Windows 7 it almost immediately goes to the GUI load screen with the windows logo. On the other hand, if I boot into Ubuntu I get a black screen for ~30 seconds before the Ubuntu logo even appears. Comparing GUI boot times, Ubuntu is clearly the winner, but they take the same time total.
Does anyone know what is making the long black screen or how to reduce the time? I would really like to show people how fast Ubuntu really boots.Immediatly before Ubuntu Gui starts, an message shows up for a second saying something like "Unknown adaptor version (2): You may experience some problems", it flies past so quickly that may not be verbatim.
I'm looking for a way to insert the number of lines in a file to the start of the aformentioned file. This should be simple but as I am not used to scripts in Linux, I am finding it tough going. I can find the number of lines in a file easily enough via
filesize=$(awk 'END {print NR}' $1)
but as for inserting this into the first line, i'm failing to do so. I've tried some of the other approaches on these forums but none so far have been able to do so.
I've tried:
sed '1i$filesize' $1
but sed i requires a string, not a variable so no go I've also tried:
mv "$1" "${1}.bak" 2>/dev/null || touch "${1}.bak"
cat $filesize "${1}.bak" >"$1"
but again with no luck as cat seems to need an input stream Just to recap, i want to insert a line at the start of a given file that holds the number of lines the original file has.
ie the file:
a
b
c
d
e
should become:
5
a
b
c

View 2 Replies View RelatedEverything was going great, updated my nvidia drivers, did initial updates etc... And everything was awesome from the boot screen to the shutdown screen.Recently (today) I installed a few updates that update manager thought were essential. However after doing so, when I restarted my computer and got to what should have been the boot screen, it simply sat for a few seconds with a few horizontal RGB lines and then booted to the login window... I have done nothing else to the pc besides those updates.Also when I shutdown I get the same few RGB lines, they are in the top area of my monitor @ a 135 degree angle.

I tried changing NV to nvidia and visa versa. Still the screen is buggered.I installed compiz checker and ran it it said all ok. My text goes large the colours are jittery ? When I go to NVIDIA XSERVER SETTINGS i can not change the screen res ? It just stops from selecting the options?

I have noticed that there are some tiny white scanlines over the screen in linux, is this something known? specific graphics cards? just an issue with my setup?

I really don't know where I should ask this question. When I'm watching a video in full screen (ex, avi or h264 file) I am seeing random horizontal bars where there is action on the video like where a head is turning.When the motion is slow I am less likely to see these lines. Faster the motion, lots of lines or shaky motion. I was using my onboard Geforce 6150 GPU but thought it was because it was underpowered. I then bought a GT220 thinking that it was the problem. It is still but less frequent. Using the built in player, VLC... I don't know where to look, what to search for...There is my setup:

I've been away from Kubuntu for a while but came back when Kubuntu 11.04 was released because it's awesome. I have a newer laptop since then, a Latitude E6410 with Intel graphics and 8GB of RAM. Everything works great, except......Sometimes when I resume from suspend to RAM, the screen flickers with thin white lines across the screen. I can switch to a tty and reboot it from there, but I'm unable to use KDE until I reboot. A lot of times resuming from suspend works without issue, but sometimes this problem occurs. I haven't figured out exactly what triggers it. In fact, the most recent time it happened, I didn't even have an application open.
I would like to figure this out because I use suspend a lot. I rarely turn off my laptop unless an update requires me to. I prefer to be able to close my lid and resume whatever I was working on later, but with this glitch I cannot trust it to do that.
I am a newbie user in Linux. I have installed a package were it has EMC2 software but when I run it shows parallel lines on the screen while running? What is the cause for it ? Should I reinstall ubuntu again? I had taken a screen shot and it will tell you what I really mean? This is the screenshot, [URL].
View 1 Replies View RelatedI have a very strange problem since I turned to kubuntu 10.4. Often, after some heavy working, my laptop works very slowly and suddenly when loading something, it locks and white lines turns all over the screen, just like curtains. Linux jumps out of KDE and logs in automatically. That's very anoying since all my work is lost and it turns back to the previously saved session.
Also, often when I boot, the load screen is also mmissed up with those white lines. The only thing I can do then is to reboot.
I tried to re-install kubuntu (in first instance, i upgraded in kpackage, then i re-installed with formatting the root en swap partitions).
I don't know how to solve it. Only thing that seems reasonable now is to downgrade, since i didn't have this problem on 9.10 (fyi: I have a dell inspiron 1501 with ATI Xpress 1150 256MB HyperMemory video card, formerly i had problems to have good graphic drivers for it on previeous versions of kubuntu (some 3d games didn't work), maybe this has someting to do with it?)
i just installed slackware 13.37 which worked fine but when i boot it up it runs a number of lines and then the screen just goes black... i can login as root blindly and start x (i THINK, judging from hdd led)... but screen stays black... its a laptop and closing/opening the lid doesnt work either...
i am dualbooting with slack 13.1 which runs fine... it switches screen res at some point during boot (font is smaller) and i would say that is the point where the screen goes black in 13.37...
I made an ubuntu live usb with a 2gb persistent casper rw using pendrive linux's portable installer. this works fine on most computers, but on my laptop, it boots just fine, but the screen is divided with little lines and overlaps slightly on the righr into the left(pic included). the laptop in question is an hp pavillion dv2000 special edition.
