Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Hi all, I just upgraded my system to Fedora 11 (64bit). When using the Gnome terminal I'll type something in and it will show up as a solid block; this happens quite frequently. Attached is a screenshot.
Coincidently I also just dropped a new GeForce 9500 GT into my system. I don't even know where to start with this one. Any help or a point in the right direction is awesome. Thanks!
uhmm. for me looks like escape sequences used to set advanced terminal features like title, background and foreground colors, etc...
You are seeing theses "blocks" because the terminal you are using does not have this capability or they are not right for this terminal.
Try to reset your prompt (where theses escape sequences lives). From the image, are we seeing a remote host ? If yes, then you have to change the prompt on the remote host, not on your local machine.
no, not your entire profile, just the prompt. To do this, if you are using bash, try:
PS1="[\u@\h \W]\$ "
it should display a prompt like this: "[username@hostname currdir]$ ".
However, having a second thought and re-reading your first post, you said this not happens all the time, just "quite frequently" what make me wondering if the problem is in another place, not the prompt.
From this terminal, run/type "gnome-terminal" and check if the problem persist in the new terminal.
In the terminal window menu bar, click on "Terminal -> Character Encoding" and verify that your terminal is using the same character encoding as your applications. (The default is usually UFT-8, but you may have changed it.)
PTrenholme, my character encoding is set as UTF-8.
marozsas, the command, PS1="[\u@\h \W]\$ ", did not work; nor did a new window spawned by running gnome-terminal.
Some more details I've noticed, when I click anywhere inside terminal with my mouse the "blocks" go back to the original character I typed in. Also, whenever the text I type in wraps to a new line the "blocks" that were on the first line disappear and go back to the original character I typed in.
I also tried changing the cursor shape to an I-beam and an underline. Attached are two screenshots of those two cursor types. (I just mashed keys to produce the problem.) It seems to be leaving behind whatever cursor type I have set in place of the character. Could this be a problem with my Nvidia 9500 GT? I never had this problem with my old Nvidia 7900. Unfortunately, I upgraded from Fedora 10 to Fedora 11 the same day I put in my new video card so I can't isolate either the card or Fedora 11 as the problem.
I just installed the "official" nVidia driver, and have started to see this problem, but very rarely.
Suggestion: Try changing your xorg.conf file so you use the nouveau driver instead on the nvidia one. (The X-server may complain about invalid GLX modules, etc, since the nVidia versions are not compatible with the nouveau driver, but I think it may work.
To try it out, make the change and then open a terminal and type startx -- :1 That should start a second X-server attached to tty8 and switch you to that new session. If you just get a blank or black screen, press <ctrl>-<alt>-<F7> (all three keys together) to switch back to the server running on tty7 and undo the changes you made in xorg.conf.
If you're switched to the new server session, see if you have the problem in the terminal window. If it's gone away, you know it is caused by the nVidia driver, or some setting you're using. I haven't checked this, but I don't remember seeing the problem before I switched to using xrandr instead on composting in my display settings, so you might want to see if changing that setting might make a difference.
Anyhow, to close the X-server on tty8, if it started correctly, just select "Logout" from the exit menu and you'll be automatically switched back to your session on tty7.
Well, changing the driver did nothing but prevent X from starting and locked up my system. I don't know if it helps, but below is my xorg.conf file. Would it also be beneficial to post my Xorg.0.log file?
And, did you try the "startx" method I described, above? The "lock-up" should have been limiter to the new X-server, leaving the one connected to tty7 function as it was.
I notice that you don't have any of the fancy nVidia stuff referenced in your xorg.conf file, so perhaps my conjecture is wide of the mark. For your reference, here's the nVidia-relavent parts on my xorg.conf:
By lock-up I mean that when I ran the command "startx -- :1" my system started the new X session and switched to it but it displayed nothing but a black screen. Ctrl alt F7/F2/F*/Backspace/Delete did nothing, so I was forced to reset the system.
I've long since wondered why I did not have any of the fancy Nvidia info in my xorg.conf. I installed my drivers by downloading the installer from Nvidia's website. I run that, it compiles the drivers, then asks me if I want it to configure my xorg.conf file (excuse me if I am being redundant here) and I tell it yes and everything has always worked for me. That being said, I just got a new Nvidia 9500 GT (a second one) today (why I have the SLI line in my xorg.conf) and X won't start when it is in my system (my thread relating to that issue can be found here). I am thinking that my problem lies with a lack of proper configuration of my drivers. Anyway, should the Nvidia installer have put all that info in my xorg.conf file for me? Is there another utility that does that? or do I have to do it manually? If so, how would I do that? Thank you for all your help. It's very much appreciated.
I got the issue with my new graphics cards sorted out. Turns out I needed to specify the BusID for each of them in my xorg.conf. I was hoping that adding a little more configuration to xorg.conf would fix this problem with my terminal but it still persists.
I had strange gnome terminal keystroke behavior. After reading this semi-fortuitous [google.com/linux "cherry picking"] column (and after reinstalling 'some' non-offending RedHat RHEL 5 packages, etc. etc. to solve my odd ' i ' behavior problem.) Reading this column put me onto going to my gnome console menu at the top and looking around.
So, I went to the terminal's edit->Keyboard Shortcuts->Edit And I saw that somehow -- or someone [I use a #trivia chatroom (but my 24/7 RedHat Network updating and security bug fixing should have caught any intrusion, right?)] I certainly did not make the change with either volition or veleity. -resuming- someone or some synchronicity-intensive event had changed my 'paste' Keyboard Shortcut, in the gnome terminal only, to the single letter ' i ' !?!?!?!
Changed it back to Ctrl+v with the help of some very good gnome documentation/programming in that console (N.B.: in KDE it did not happen, maybe that fact should have given me more info than it did... next time I'll try ratiocination more vigorously.) Now I'm good to go.
I was bummed out. [Not a good thing, you will tell me, for a programmer / SysAdmin to allow him/herself to enjoy: shame, visions of "The Complete Dummies Guide to __" which series is possibly a typical cunning excuse-pregnant tactic of the _______ party; or anger, frustration, creeping rumination of low self-worth...]
e.g.: Yesterday, I fixed a kitchen plumbing problem two minutes before a housing inspector arrived. I am not a plumber; but I am becoming a better problem solver. "He fixes radios by THINKING!" (--Richard Feynman quoting someone else in re. his capabilities showing up early-on.

FedEx next time. Maybe these represent the _____ party's tactics. In situations in history such as the current "political" scenario, intellectuals and books 'go', or are targeted first.

BACK TO MAIN THEME: John Paul Sartre said (yes, this applies, admin/moderator; respectfully -- it may even be "key" <--humor **"I have never thought myself the possessor of any special talent, rather I have applied myself to Work and faith." (possibly Faith for myself, gobiigloo: both.)" [**Fairly close paraphrase.]
