When I press the calculator key on my keyboard and the calculator comes up, I can't use my mouse anymore. I can move it but I can't click on anything. Is there a fix for this?
View 4 RepliesI am using an Nvidia GeForce FX5200 card and nvidia hasn't released a driver that seems to work with it in Fedora 13 yet.. However, I decided to do an install of F13 and use the nouveau drivers until Nvidia updates their drivers, however, the nouveau drivers don't work worth a crap with my card I did a fresh install and then ran a yum update. What I am seeing is after a few minutes, all the icons disappear, no fonts, and nouveau starts throwing errors to my message log. Here are the messages I get:

I am completely new to Linux in general, and have recently downloaded Fedora 15 KDE spin. I tried dual-booting between Windows 7 and Fedora by shrinking one of my Windows partitions (I have two, this partition not containing the Windows installation). I tried shrinking it to 30 GB less than the total space available on the partition, and after pressing continue, received an error (which I unfortunately dismissed quickly and can't remember). In the file manager, Fedora showed that my partition changed from 1.3Tb to 1.2 Tb, but I couldn't access it. Upon rebooting into Windows, I still can't access it, receiving a "format drive before use" popup and then error stating that it is possibly of a different filesystem or corrupt.
Unfortunately, I stupidly didn't backup any of my data (which I will be sure to remember to do in the future). I installed EASEUS Partition Master 8.0.1 Home Edition, which states that my drive is still of NTFS filesystem and has the total space it should. However, upon clicking "check drive," it states there are no errors and when trying to "explore files," it doesn't find any (yet it shows the correct amount of used and unused space). I then tried running TestDisk, but only allows me to check my media drive E, which is my dvd drive that has my Fedora Live CD in it (which cannot be ejected manually or through Windows, an error stating it cannot be ejected). I didn't go through with TestDisk for my DVD drive because I needed to verify the type of partition (which to my knowledge shouldn't even exist). It shows 700 something MiB / 600 something MiB. Although I have decent general knowledge about computers, I am a complete novice when it comes to doing something like this.
I have two monitors set up on my Asus N61J laptop, but have a weird problem:When I move the mouse to right-hand edge of the Left (Primary) screen, it disappears. To get it back, I have to either keep moving it to the next screen, or move it over something that will cause it to change shape.It also happens if I move it to the left-hand edge the Right (Secondary) screen. Anyone have any ideas as to how I can fix this? It's a little annoying, as it makes it hard to select the Logout/Shutdown/Status menu
View 1 Replies View RelatedI recently bought a second monitor and I had this set up perfectly fine with two panels on my primary display and one on my secondary. I've now gone away for the weekend (leaving the monitor) and I went to turn on my laptop and it didn't work.
When I login to a gnome session (or indeed a failsafe gnome session) I just got two horizontal white bars (where the panels would be). I switch to a terminal, login and run top and see that gnome-panel is on 100%. Running 'killall gnome-panel' does nothing (tried a few times).
I've had to install xfce4 just to type this message. Is there any way I can 'reset' gnome-panel or any other fix? Or even a workaround would be nice. I'm on 9.10 by the way. I am going to upgrade at some point but its not really an option yet.
When I try to launch the Calculator from the Applications menu I get the "Starting Calculator" tab in the bottom panel, but the application never launches and the tab disappears after a few seconds.

View 5 Replies View RelatedI'm currently reading math courses at home, as opposed to doing it in school, and Swedish schools recommend getting a TI 80 or TI 83 calculator for these math courses. If I'd actually buy one of them, a TI 83 would probably be a better choice since it would last me through more courses, but for now a TI 80 calculator is enough. They are graphing calculators, for anybody that doesn't know.
Anyway, since I'm reading at home, and these calculators are a little expensive, I was looking at software to replace them... The gnome calculator that comes with Ubuntu is a good start, and is probably almost enough for what I will need for now, but it lacks the graphing capabilities, which I will need.
Is there either a more complete calculator, or something to complement the gnome calculator, that will suite my needs? I know I could look through all of the calculators in the repos, but frankly it takes quite a bit of time.
I want to know if it is possible to edit the source code of the programs in Linux. Like, take the calculator for instance. If I want to add a user-defined function to it, how can I do it - if I can do it at all? In general, where and how can I look at the source code of such programs ?

Ubuntu 10.10 default calculator, gcalctool 5.32. seems to be missing the 10 memory registers it used to have. The geaphic keys for memory functions are missing and control-M does not bring up memory pop-up either. Am I just missing something or have they been removed? I store lots of intermediate results in the registers for use later in calculations.

Like my title states, Compiz or any desktop effects aren't usable for me in 10.04. Never had any problem with any previous release. I'm using the open drivers with my ATI 1950 GT. At first I thought it was due to the fact that I have dual monitors now, but after disabling one and trying again it still acts up.
All I can explain it is it's as if my desktop were "lagging". My mouse cursor will jump and stay in a certain area and I can only move windows a short distance before my mouse pops off and the window jumps back. Minimizing windows also seems like it's a burden on my computer and will take a few seconds to do so.
This is the same setup I've had over various distributions and this is the first time I've experienced it. Anyone have any idea if it's fixable or if my computer is just finally getting too old? I can post the rest of my specs if they're needed.
So if we don't like Unity or the way it crashes with alarming regularity, the fact that it requires multiple mouse clicks to do things we used to do with a couple and the fact that the launcher is not configurable in any meaningful way, we can always go back to Ubuntu Classic, right? Wrong!
Trying to enable desktop effects in Classic under amd64 and NVidia proves something of a nightmare.
1. There is no 'Desktop Effects' tab anymore. We are told that this is no longer necessary as Compiz is running by default.
2. Jockey reports that the NVidia driver is installed and that the driver is activated but 'not currently in use'. This is a bug and has been reported. However, this could tempt people to uninstall and re-install the driver (I am one of these) with disastrous results.
3. Trying to enable things like the Cube and Cube rotation break Compiz and remove *all* the settings in CCSM. Window menus and borders disappear and have to be restored by resetting the Window Manager to Metacity.
4. Getting applications like Radio Tray or Shutter to show in the System Tray involves circuitous circumventing of a 'Whitelist' (which is there for our protection because we shouldn't really want to use applications which put icons in the tray!) is really going to put off people installing applications which then apparently don't work. (They do work, they just become unusable because you cant see them or do anything with them!)
5. Skype will sometimes load and sometimes won't. Sometimes the sound is corrupted and sometimes not. Despite the fact that Skype is proprietary software, many people need to use it. If it becomes unreliable many people will look elsewhere or go back to Wingedows.
6. In both Unity and Classic the task bar will randomly freeze and become unresponsive, requiring a reboot.
Natty Narwhal? More like Natty Dread at the moment. I dread turning it on and it is dreadful. I'll try Gnome 3 or go back to 10.10. I can no longer recommend Ubuntu as a viable alternative to Windows to my customers.
snappy title to grab attention. maybe not stupid, but bleeding difficult to use, talk about a non-obvious, non-intuitive interface; I want to enter a hex value, and have the calculator convert that to decimal. So, I use the pull-down, choose 'hexadecimal', enter the hex value, then change the pull down to 'decimal', expecting to see the decimal (base 10) value. What do I see? The display just adds the hexadecimal base to the end of the hex value I just wrote! Where's my decimal (base 10) number damn it? I can't for the life of me work it out.
View 4 Replies View RelatedI've been using Ubuntu 10.4 for nearly a month now and am very happy with it, especially the ability to add and upgrade programmes which up till now was a nightmare with worries about dependencies etc. I do have one major gripe, and that is Firefox 3.6.3. I gather others have had the same problem. At start-up Firefox works fine, but after about 12 hours, it becomes so sluggish as to be unusable. Web pages that would take seconds to download now take minutes and the hard drive starts churning and grinding away. The whole system becomes slow and sluggish, and when I do a "top", Firefox is right at the top. Very often the only way to get out of this is to physically turn the machine off and then back on again, which I know is a bad thing.
Its not as if I am overloading Ubuntu. The last time I had to switch the PC off, all I had running were 2 terminals, a calculator and gedit. Firefox was running about 10 tabs. Even when I do a kill -9 pid on firefox and then restart it, within minutes, the system is grinding away and slowing down. The only way to remedy this is to switch the PC off. Someone else who had this problem says its as is Firefox is getting tired and needs to refresh itself completely. Is there any solution to this problem as I gather others have been experiencing it.
I recently built a pc to run 10.04 and EMC2 from linuxcnc.org I havent even gotten to the point of trying out EMC2 on this machine because Ubuntu runs so slow. The build spec's are as follows:
http://www.geeks.com/details.asp?inv...714-CEL24-PB-R MS-6714 mobo
Intel 2.4ghz celeron processor
2x512 PC-3200 patriot ram
using integrated graphics
40gb Maxtor IDE hd
I installed using the live CD downloaded from linuxcnc.org and Ive used that same cd multiple times so I know that's not my issue. Now to my problems. The computer runs, just very very slow. Opening 2 web pages at the same time takes 2-3 minutes, and if there is a lot of pictures or content there's no point in trying. Running EMC2 works ok, but if I open a complex program in the viewer all bets are off.
Since 11.04 was released, I've used it in Gnome and now also KDE, and this problem is in both. Aptitude is completely unusable. The main issue is that when downloading packages, it disconnects every minute if not every half a minute, making package installing a very hard process and making the configuration of a new OS take days (just to install 1GB of packages). Ontop of the disconnections, aptitude doesn't even want to go full speed when it IS connected.
The other issues involve repositories. Whether it's the official Ubuntu package servers, ANY of its many mirrors, or even my own custom PPAs, connecting to ANY repository when I reload my packages is a hit-or-miss, and it's completely impossible to get them all in one refresh (in fact, I don't think I've been able to access the main server since upgrading. Ever. I've been on the US server). This makes installing all of my packages take even LONGER. Also, to add insult to injury, the list files in /var/lib/apt/lists constantly corrupt themselves and make themselves unusable, ESPECIALLY the PPA lists (anything that uses launchpad has to be disabled at all times unless I have to update its program, or else I have to delete those list files every day).
Googling any of these issues separately gets me nowhere, so I'm making a topic, and it better not be the millionth topic I've made here that never got solved. The problem can't be my router or modem because my brother runs aptitude just fine on his 11.04 laptop. This issue is within my computer.
I meant apt-get. You mean they aren't the same program with two ways to run them? Yes, apt-get is the problemed one. I never actually type "aptitude" into the Terminal. As a consequence, Synaptic and KPackageKit and any other apt-get-using program is messed up as well.
this time last week I was happily running 10.10. I decided to upgrade to 11.04 via Update Manager (not a fresh install), and of course I didn't like Unity so gave Gnome3 a shot.
Well.. at this point the system would stall whilst booting.. so I downloaded the 11.04 disc and reinstalled it (I desperately need to keep my data and don't have any backup options at the moment).
But, now when I boot into Ubuntu (using an Acer Aspire 5741), the resolution is about 800x600, and the mouse doesn't work. Has anyone got any ideas how I can force Ubuntu to reconfigure the system as if it was a completely new install?
I have an old Dell desktop that normally runs XP. It has 512mb of ram and I think its a Pentium processor. From what I understood Linux is a simpler, and more stable and efficient OS so I figured I'd give it a shot. First I tried the Wubi installer and got nothing but error messages after the install and it kept freezing and eventually just wouldn't boot at all. So then I tried the full install from disc. Better at first. I soon discovered all the customizable themes and went a little nuts trying to make one user exactly like W7 and the other exactly like OSX leapord just for fun.
I noticed significant slow downs and after some research I came to find that it was taxing my old graphics card. So I setup a user with no changes, still really slow. Then I deleted and reinstalled and I'm now using the bare bones UI. Its still really, really slow. I get lots of mouse drag and just now it took about 7 seconds for the applications window to drop down and 35 seconds to open the home folder. Also about 10 seconds for right click window to drop down.
I'm trying and I really want to like Ubuntu but as of now I'm finding it unusable for even the most basic of computing. I realize my computer is old but xp still runs like gangbusters. So maybe Ubuntu is designed for more modern hardware and more ram, am I screwed? I was looking forward to playing around really customizing my GUI but more importantly I was planning on putting on my girlfriends laptop with similar specs. Her computer needs a reformat but she doesn't have the XP disc. As it stands her XP is still much more usable even with all the viruses then Linux is as a fresh install on my desktop. I don't want to delete xp and end up with a slower linux.
I have encountered the strangest bug, filled with so many inconsistencies that I am unable to comprehend why or how it is happening. It has only happened once and whilst it seems to resemble another bug that I found when looking for this one, it is fundamentally different. Here are the facts:1. I am using an Acer Aspire One netbook.2. This netbook is running Ubuntu 9.10.3. It has been running Ubuntu 9.10 since the first time it was released as stable.4. Yesterday, whilst I was engaging in an intellectually stimulating debate through the convenience of Pidgin, I encountered the said bug with the following attributes:The keyboard has the appearance of not working.
But if one applies a lot of pressure to each key, one is able to type.This bug is not resolved by a system reset.This bug does not affect my BIOS or even Ubuntu until I log into the particular account where it first happened.When I log out of the account and log into another one, my keyboard is perfectly responsive.When I log back into the "damaged account", the keyboard is once more unusable.The right click menus do work, in stark contrast to another, similar bug, the report of which I encountered in my search for this one.So, clearly, an undesirable workaround would be to migrate to a new user on my system. This, however, does not change the fact that I do not wish to do this another time if the bug repeats itself. Furthermore, if it is only active in a session of the "damaged account", it is likely that it is a configuration error of sorts, no? I have another strange configuration error on that account. The little icon that allows me to choose to which wireless network I wish to connect is random in when it chooses to appear or not, although the service is active (as I am greeted with a message directing me to click on the non-existing icon in order to select the network...). Yet again, this only happens when logged into a particular user, while other users seem completely unaffected.
What I conclude from this is that Ubuntu's configuration system is pretty erratic and it makes seemingly random yet seemingly irreversible changes to user configuration. I would not even know where to start when faced with reading through different configuration files. Furthermore, I would feel as though my PC were constantly working against me. It is a strange feeling, when I bought it with the intention that we might work together.
I'm using 9.10 Desktop 64bit on a Dell Latitude D830. I have 4 gigs of RAM and a 7200 rpm sata hard drive. Everything works pretty well, video, sound, and network. Flash isn't as smooth as in Windows but I assume that's a Flash/64bit thing and not necessarily an Ubuntu thing.
However, one area of performance still lags far behind my Windows XP experience, and that's disk writes. For instance, when I'm copying a large amount of information from a USB drive or from my Windows partition to my native partition, I can barely switch windows until the task is complete, nevermind trying to surf the Web. I thought that that might be related to the slow performance of the ntfs driver, but recently I have been doing a lot of work with VMWare, and I get the same result when trying to pause virtual machines - it writes a largish amount of information to disk in a short amount of time and I can't do much until it finishes.
Here are some things I looked at based on other threads to try to debug my issue:
~$ sudo hdparm /dev/sda
/dev/sda:
multcount = 8 (on)
IO_support = 1 (32-bit)
readonly = 0 (off)
readahead = 256 (on)
[Code].....
That disk read speed is a little faster than average - several more tests showed it hovering around the 66 MB/sec range. Of the other info, I see that UDMA is on which I understand is good, but if there is something else there that I should fix I don't see it.
I know that my computer can handle these tasks (at least the vmware stuff) without such a significant interface slowdown because in XP I did it with less RAM than I have now. Is this just the way that the linux kernel scheduler fails to account for UI needs?
I've been using UNR since the 9.04 release on my Eee 1000HE and have been generally happy with it as a solution since then. Tonight I've upgraded to 10.04 using the package manager and everything starts correctly but when I start any application it minimises itself straight away making the system unusable. If I click on the application to bring it to focus, I get about 1/2 a second of typing before it minimises itself again. Using that method I've been able to get around the problem with a sudo apt-get remove netbook-launcher - but I like the netbook launcher and I'd like to keep using it.
