Ubuntu Servers :: Manual Pages Don't Display Correctly - Keyboard Functions Incorrectly Via VT100
Sep 17, 2010
I have gotten my project ubuntu server 10.04 up and running and logged in remotely with a terminal emulator program called AccuTerm that I use from work. It has multiple control files and want to know which file works best with ubuntu server. My reason for asking is some of the manual pages do not display correctly and keyboard functions seem to function incorrectly via VT100 and I have eighteen to choose from?

I'm trying to use kchmviewer to look at a few eBooks but its rendering the pages incorrectly. Black text on black background. I heard that kchmviewer is the only chmviewer with a decent GUI. Does anyone have any alternatives?

I cannot find the C library manual pages on fedora 11. Are info pages the same as man pages?
or how can I install man pages so that I can use man 3 malloc?

Is there a way to select a second installed OS on a home server system without display and keyboard? I am putting together a home server (for mail, storage, media streaming) using an Atom-based Ubuntu Server 10.04 on a 4 GB intern flash drive and 2 hard drives for data storage, but no display or keyboard. I want to make periodic full backups of the system (flash) disk and use a second OS (installed on a partition on the hard drive) with a graphical interface (e.g. Xbuntu or PartImage) for maintenance purposes. I can connect remotely (from a Win7 or a Linux computer) to the X-display once the second system is running.
a) how can the second OS be booted on this server without keyboard? Is there a way to tell Grub2 to look at some hardware switch (or file) for the menu selection? The board has a serial and parallel port so I could wire up a switch to some pin of one of these. Also external USB connectors are available on front and back. Or can Grub2 read its default OS choise from some simple file, easily to change from a shell command of the eBox webbased system control internface?
b) I assume the second OS is needed to make a complete backup of the server OS on the flash disk. Can the backup be automated? (i.e. switch to second OS, backup, reboot first OS)

I have an Msi Wind u100+. Between the right hand Alt Gr and CTRL keys there is a key that looks like a menu. It seems to have the same function as a right mouse click. I want to know how to change this specific keys' function, such as use it to launch a terminal or another Super key. Ive tried Keyboard Shortcuts but its main right click function prevails. Also, searchng the forums and google only brings up how to change the entire keyboard layout to DVORAK or something and that's not what I want to do.

I installed Ubuntu 9.10 on a new acer emachine e525. All is fine except that now I cannot switch the wireless on as the button above the keyboard no longer functions. Can anyone tell me what I can do to fix this as wireless is obviously vital in a laptop. BTW the wireless waqs working fine while the machine had Vista on it.

Today, just hurry the boot process up a few seconds, I manually selected the kernel to boot to. Everything went well and got to the point where I heard the bootup sound and then the screen went blank and my monitor on-switch went orange - indicating nothing to display.
If I pressed the delete key I could hear the sound made when there's nothing more to delete. I switched to one of the virtual terminals and the monitor switch went green but no display.
I rebooted and let the bootup process as normal and everything was OK. I repeated the initial bootup process, with the manual selection, and it went blank again. The odd thing is, I'm sure I've recently done this before and all was fine.

So I'm teaching myself some scripting to try and create a fairly simple photobooth type affair... I've got gphoto2 playing fairly nicely with my canon, and imagemagick taking that output and rearranging it to a vertical format...
EDIT:
*smacks forehead*
Fairly simple to do what I needed initially: Code: feh -FZ -D 1 --cycle-once $COUNTDOWN & sleep 2 &
feh -FZ -D 20 --cycle-once $SMILE This shows a countdown from 5 to 1 in images and $SMILE is big that says 'smile'
So my question is thus... (fairly basic but I can't get my head round the use of & and sleep in this context) what's the best way to call my gphoto instructions (or a script with them in) mid way through the above code?!
'feh code'
sleep 5
'gphoto code'
this kind of thing seems like the way, but the'sleep 5' and 'gphoto code' doesn't start until feh is finished in this case?

I have got four webservers and one fileserver, all running Karmic and kernel 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64 GNU/Linux.A folder on the fileserver has been exported using NFSv3 with these options: rw,async,no_subtree_check
and mounted on all four webservers with these options: efaults,rsize=32768,wsize=32768,noatimeThe webservers run Apache+PHP+APC. Some php-files include other php-files from the nfs mount, and are requested by users very frequently (~ 100 times per second). Sometimes but not always if I alter an included php-file using FTP (the FTP server is ProFTPD and runs on the fileserver), the file seems missing:user@webserver1: ~ $ ls --full-time -al /path/to/included/file.phpls: cannot access /path/to/included/file.php: No such file or directoryI can repeat this command for hours, but the file keeps missing. Until I query the directory:user@webserver1: ~ $ ls --full-time -al /path/to/included/ | grep file-rwxr-xr-x 1 1002 1002 14294 2010-07-04 21:11:30.000000000 +0200 file.php

I've got a couple of new hard disks that I have partitioned (3 partitions per disk) and set up in a mirrored software raid array using mdadm. They've synced, I've put file systems on them (1 x ext4, 2 x luks + ext4) and I can mount them. I've checked the partitions using fdisk. I've checked the filesystems using fsck. So far so good. Next step is that I'd like mdadm to automatically assemble them on boot. (Not bothered about mounting and crypttabing yet.)
I've used sudo /usr/share/mdadm/mkconf to generate a new mdadm.conf with the appropriate UUIDs for the new partitions. I've checked that this matches the output of sudo mdadm --detail --scan
The new lines in this file are:
ARRAY /dev/md9 level=raid1 num-devices=2 UUID=470fb8a6:45561fe0:ebda4a02:9ba7a1ed
ARRAY /dev/md10 level=raid1 num-devices=2 UUID=f351fbba:c704a4b2:ebda4a02:9ba7a1ed
ARRAY /dev/md8 level=raid1 num-devices=2 UUID=c6ccec17:2274588e:ebda4a02:9ba7a1ed
To check that the mdadm.conf is fine I have stopped the new arrays:

I recently migrated to a newer server running centos5 and cpanel
I have imagemagick installed
I installed freetype as well
Most images display fine on web pages for accounts on the server, however, .gif images do not display.All I get is an image placeholder.
.png are fine
.jpg are fine
I have not tested all the possible varieties of images, but .gif I know is not displaying.I am sure its some kind of RPM I am missing or a configuration problem.

Keyboard repeat doesn't seem to work correctly on my system (Xubuntu, 9.10). Holding a key down ends in the repeat function stopping after a certain point, and at different times each time. Also, editing text fields is tricky because the field currently highlighted reverts to its previous value if I don't hit enter fast enough (I have to type new values into a notepad and copy and paste it quickly into the field).

I am experiencing a problem which I lack the knowledge to crack at this stage. I run a home server (2.6.28-19-server #64-Ubuntu SMP) which firewalls and proxies for my LAN (including 2 linux boxes, a vista box and a win7 box).Most of the time this works well. Very occasionally we will run into a website which will not display at all on the LAN boxes.Examples: for a long time I could hit the forums.egosoft.com site but not the egosoft.com site. Now my wife can't hit www.boden.co.uk. I'm pretty sure that the problem is in the Squid3 config. solation testing:Run the vista box direct into the ADSL modem: get the website.Hit the website using Lynx through SSH on the server box: get the website.Try to get the site on a browser (have tested with IE8 and chrome) on any of the win boxes through the proxy - no joy. DNS error.Firefox on Ubuntu desktop from the linux client boxes gives an error message about an unrecognised form of compression.I can only assume that I've misconfigured the Squid3 proxy in some way - it works for 99% of sites but fails utterly on others.

I am having problems with Thunderbird in Ubuntu Lucid. I am not sure since when. It could have been since I upgraded to Lucid from Karmic. When I open Thunderbird, a message pops up that is supposed to ask me for the password. However, it is all blank inside and doesn't display the text. I found that after I click on ALT+TAB a few times, the message displays correctly. This is very strange. Is anyone else having (or had) the same problem? Does anyone have an idea for a fix?I tried uninstalling and then reinstalling but it didn't work out (I didn't "purge" though).

I have a problem with getting the picture to display properly on my HDTV. Using the regular driver (whichever that is) the picture displays flawlessly, but when I'm using the NVIDIA driver it displays really weird. URL...As you can see the top and the right of the picture is missing, and there is a large black bar to the left of it.Since it only does this with the NVIDIA driver I guess the driver is at fault here. The graphics card is a 8400GS and I'm running Xubuntu 10.10. The HDTV has a native resolution of 1366x768, and I've connected to it using HDMI.
I have tried messing around with overscan compensation in nvidia-settings, but it didn't help much.What can I do to fix this?

I just tried changed the port that apache runs on from 80 to 8080 (I need port 80 for a difference service so I am changing the apache port). After doing this I load 127.0.0.1:8080 in a browser and get a 404 error generated by apache, if I change it back to 80 it works fine.

I recently installed KDE and began using that instead of Unity (less buggy, IMHO) and it was running smoothly until I began configuring my GTK applications for transition in that. I installed the Oxygen-GTK them from gnome-look.org and set that as my default theme for GTK applications under the KDE appearance preferences.
When I log in, however, GTK applications just use the stock Xorg theme until I run "gnome-appearance-properties" in my terminal.I believe that a fix involving .gtkrc would suffice, but I honestly cannot configure it no matter how hard I try.

I have a laptop that doesn't display correctly since installing F10 x86-64. Instead of using the i810 driver, I see the experimental intel driver. I am running on a Dell D630 laptop with the default intel integrated graphics.
Just to note: Running gnome. I tried KDE and I can actually get this to work and display in 1600x1200. I don't want, "well use kde then" to be the solution. Also, in gnome, if I go to the screen resolution option from the menu, the mirron screens is clicked. Even when I detect monitors and unselect the mirror screens and pick the correct resolution, when I click OK, the screen flickers, and I go back to the same screen with the original default values? Wierd.
I got the bright idea to install system-config-display (something like that), which installed fine. I then changed my default resolution to 800x640 just to try it (really want 1600x1200). Well, I decided to reboot. Not the laptop doesn't start, it stops right after loading anaconda, and just won't go any further.
So two questions:
1. What do I need to change to get the laptop to actually boot?
2. How to get the external monitor to display in 1600x1200.

This is strange that I actually can't use the command "man vi" while, "man yum" is in use... How can we get the whole manual pages for dev in Fedora just like what we can get in Ubuntu? I am really sorry for this post. I didn't see the rules clearly. But I can't delete it now... I found the answer for this question in the Internet by myself...... In the software manager, find the "man-pages", install it. That is how I fixed it. Maybe we can just type the command: yum install man-pages.

We are using a program who connect to other server using xterm over telnet. Our programmer needs to migrate t vt100 over ssh (why... I don't know cleary, but we prefer ssh because is more secure).But we have problems with some keys. If we press F8 program use another convination of keys and we can't find the way to modificate it.
Actually we are using something like that:
Down: (byte)0x1B, (byte)0x4F, (byte)0x42
PageDown: (byte)0x1B, (byte)0x5B, (byte)0x36, (byte)0x7E

installing a Linux distro on an old mac to make a simple desktop home computer details below.The Scenario: I am trying to breath a couple more years of life into a computer illiterate friend's Mac G4 [POS] computer, it is a paper weight but all he needs is a basic desktop and an web machine and he can't be made to buy a new one unless all other options are exhausted.
The computer: Is a Mac G4 power-PC architecture, 450 MHz, 18 GB HDD, 1024 Mb ram ugly little thing that was gotten for free it currently has mac OS 10.2 [unsupported] and newer OS-X (he is more familiarized with Mac) don't run on power-PC. Currently web pages don't display correctly, flash and other plug-ins and web scripts don't operate and it is very clunky with software bloat.
My solution? Is to install Linux so he can have a trim clean operating system. Ubuntu 10.04 [community ppc variant] runs off a live CD but is dead slow on account of the low processor power and I was unable to get gnash to run flash video a necessity as Adobe has abandoned power-PC, I suspect the gnash error is between chair and keyboard, advice is welcome. I would like to install a distro more suited to this system currently I am looking at mintPPC but can't quite follow the installation instructions what is meant by Debian squeeze the download link gives me a mini.iso is this the same thing? Also clarification on the terminal commands would be of help. Advice on a different distro is also welcome preferably one with an all in one installing process rather than the mint, Debian, Ubuntu multi-part thingy that mintPPC is; it just needs to be power PC compatible and able to run on a few hundred MHz maybe there is an easy way to put LXDE or Xcfe on a more popular Disto? As for me: I am a new Linux convert, discovering the glory this past July and am still learning my way around I am computer literate and somewhat savvy but I am not a tech head and I HATE working on them I can and do it but I don't like it and I am often hampered by ignorance of the latest new/trends and an acute allergy to Macs and Apple products in general.

I recently dist-upgraded from Debian 5 to 6 (squeeze). Since then, the xclock I run from my window manager's start script isn't displaying correctly (it displays only a "0"). The thing is, if I run the same command in my start script in my terminal, it works just fine, as it has always done...
I use this rather "old" X applications because I like my programs simple/not buggy/fast, and it's resulting a rather annoying problem (being that apparently nobody else has it...).
All other programs in my start script (gnome-terminal, emacs, xmodmap, etc) are working with no problems whatsoever.
My window manager: sawfish
Command to run xclock in my start script:
Code:
xclock -digital -brief -geometry -0+0
Attached picture:
Top: xclock initialized by start script
Bottom: xclock initialized by terminal
