[Arch Linux] This has been mildly annoying ever since I installed Arch. From X, I can switch to any of my ttys, using Ctrl+Alt+FN. But when I'm in a console, that key combination does nothing, and I have to restart X11 to get back.

Gnome-failsafe and XFCE work great. xsession-errors: [URL].... i also cannot switch between ttys, if i do video becomes blured to the point of unreadable. I think this is an issue with X. I have tried the generic kernel (non-pae) with noapic and apci=off with no results.

Edit: Very strange, After I installed the NVIDIA drivers, It is OK...
As everyone knows, the graphic user can be swithed with Ctrl+Alt+F7 (or F1 in Fedora). There are also a few text mode consoles - Ctrl+Alt+F2...F6.
Fortunately, there is a Switch User button when the screen is locked from Gnome with the default screensaver.
The question is how can a new graphical user be switched from console (Ctrl+Alt+F2...F6) if the screen is locked by some other screensaver which does not have this function?
Just upgraded to maveric desktop and can't switch to console no longer. Pressing ctrl-alt-f1 etc pauses the screen and removes the mouse pointer, the console is not shown. Pressing ctrl-alt-f7 unfreezes the screen again and shows mouse pointer.
I know it doesn't happen to many other people but happened to me. Any ideas how to troubleshoot/fix?
How to access console of a switch having rj45 on switch side to db 9 female on pc side console cable which needs to be connected to one console server having rj11 on its side and db 9 female on other end. i.e. on switch side, console cable has rj45 and db 9 pin female connector on other side of the console cable which has come with switch. Now I have to connect this switch using console server which has a cable having rj11 on that server side and other end is db 9 pin female. Now I have to connect switch serial console cable to console server serial console cable using some converter or some cable which can connect both db 9 female connectors. How to do that? I have linux as os and minicom and console utilities.

I'm having difficulty switching from GUI to console mode. I use ctrl-alt-f1 and the screen goes blank and I see a flashing cursor but I'm unable to do anything. I can switch back into GUI mode using ctrl-alt-f7. Also at times I see the word Ubuntu with 4 dots and 2 of them are orange if that's of any use. Like the initial boot loading screen.
I've tried going back to the default display drivers and that hasn't solved it. I'm using a CRT that's connected up to my display card via a VGA > DVI converter. *I've just checked and I can't get into recovery mode either
not sure exactly when this broke, but for some reason I'm not able to use CTRL-ALT-F1 anymore to fall back to the first virtual console.I can kill X with CTRL-ALT-BACKSPACE just fine, but I'd like to be able to get a normal shell to kill things when I've messed too much with graphical stuff.

I have three Suse Linux pcs on my network.
I'll call them desktop, media center and laptop.
I am logged in to my desktop , I want to open a new session and log in to my media center.
From GUI, I select application launcher - leave -switch user and get a fresh kdm greeter screen.
On the Greeter screen, I select Menu - Remote Login
A window opens displaying three machines - my desktop, my laptop and my media center.
When I move the mouse into the new window to select the media center as the new target machine, the window immediately closes.
I have Xdmcp access enabled in kdmrc on all three systems(and rebooted).
This did work fine back when I was on KDE45 and KDE46.
Is there a new permission or setting now under KDE47?
I can't switch from tty to tty. When I start up (I use startx for X) I can't even switch from tty1 to any other tty at all. When I'm using KDE, and I switch to a tty I have to use Ctrl-Alt-F*. When I do, it switches to the tty and after that I can't switch back to X or any other tty.
View 9 Replies View RelatedI have searched the web, tried getting support on IRC, and even tried some drastic measures that I came up with on-the-fly, but could not get satisfactory results.After installing the 2.6.31-20 kernel, I have noticed, that virtual terminals ( or whatever should I call those. The ones that are accessed by ctrl+alt+[function_key]) stopped loading. When I open any of them I only see a cursor and nothing else. I can take almost no actions: the only two things that actually work are changing between terminals and ctrl+alt+delete.
Eventually, I gave figured out, that this happens because getty is not launched automatically. After running appropriate command, each terminal can be recreated for the current session. Tried fixing this by creating a script that would run that command on each startup, but could not actually make the script to be executed (I tried making rc to run it, as I need these terminals to be present when GUI is not yet activated).Right now, I see two possible solutions: either make them autoload like they are supposed to, or work out a way for that script to be ran on startup. So, any ideas?Ah, yes. Also, the GDM now loads on tty2. Will it give me problems if it continues like that?
I'd like to know how to leave only tty1 and 2 and permanently disable others. (I'm running Lenny/i386).

My wireless switching mechanism has just gone the way of the saints but Belkin has supplied a software solution for this occurrence.

What I need to know is there a similar app for the Linux computer. (NB I have tried Synergy but have no idea how to set it up - I've been told that synergy might work).

I'm trying to complete the porting to RHEL 5 of a commercial application that we've had running on AIX and SCO for decades. It originally ran on dumb-terminals, and even now runs on dumb-terminal emulators that run on Windows. We have thousands of customers, many of whom we'd like to migrate to Linux. We're pretty much done with the port, with the exception of this little glitch we're having with pseudo-ttys...
Our app utilizes pseudo-ttys, such that sub-portions of the application run under a screen manager that provides for screen-switching of multiple instances of the sub-apps on non-GUI terminals, some of which are still running serial. In this regard, it is not unlike the GNU "screen" program. However, it also supports file transfers over serial links using zmodem, and requires the ability to switch in and out of a fully 8-bit transparent mode where the screen switching keyboard commands must be ignored.
On AIX, we're using the BSD TIOCUCNTL (UIOCCMD) capability to send commands from the sub-app to the screen manager. TIOCUCNTL provides custom user ioctls and is an ideal way to solve the problem. It is not implemented on Linux, and the "alternative" of TIOCPKT does not provide arbitrary ioctls so at best we'd have to commandeer some of the existing TIOCPKT ioctls for our own use if that's even possible. TIOCPKT seems like a hack, it apparently was implemented not as a general mechanism but to solve problems specific to rlogin/rlogind.
SCO didn't support TIOCUCNTL either, so years ago we used the SVR5 alternative of putmsg/getmsg. This is a streams-based mechanism of sending control information over streams separate from the data. While RHEL 5 seems to have man pages indicating these commands exist, and in fact you can link programs using them to libc without errors, they are apparently stubbed out and return "function not implemented." This seems to be, according to this Wiki, due to certain Linux factions deeming that streams are "technically inadequate":
Certainly, I would agree that a streams implementation that is incomplete is undoubtedly "technically inadequate."
At the same time, it would appear that the SVR5 method of pseudo-tty is now the recommended implementation, the BSD one being "deprecated" (not to mention, also incomplete on Linux, given TIOCUCNTL is missing):
So here I am trying to figure out how to solve the problem. I have found a library that apparently implements the getmsg/putmsg commands for Linux, called libLiS. However, according to IBM, it has a problem with SELinux:
We've had to disable SELinux for other reasons anyway, so this is not a show stopper for us, and I am actively exploring using it as our solution. However, I've never been exactly crazy about the idea of depending on disabling security features to make something work. But, there's something to be said for the compatibility it would offer for our apps.
However, it occured ot me that we are probably not the first to have this problem, and was wondering if perhaps there is another solution that we should consider.
It has occured to me to use named pipes, but this would be rather ugly--we'd have to maintain a directory full of hundreds of named pipes, probably named after the associated ptys that the sub-apps could use to issue control commands to their screen manager, and the manager would have to monitor these pipes for commands, etc.-- certainly possible, but it seems like it might be re-inventing the wheel a bit, or at the very least, is a somewhat kludgy work-around to the apparent lack of any user-customizable control mechanisms in the pseudo-ttys. And we'd have to support it in addition to the code for the other methods since those platforms aren't going away anytime soon (SCO death-throes notwithstanding).
After the 10.04 upgrade all my CTRL-ALT-F1-6 terminals are squished up at the top of the screen. it's as if the vertical was pushed all the way to the top. You can't read anything. Here's a picture of it.http://imgur.com/7FKGoI'm running Nvidia binary drivers and everything seems to work great otherwise but I can't even find one person with this issue.

View 5 Replies View RelatedOn my terminal only system ( no Xorg or guis ) I have a font rendering issue. In place of some symbols ( eg double-lines and some other miscellaneous line-drawing shapes) are generic diamonds. Attached is a fbgrab ( png format ) of elinks showing the problem. I have now configured elinks to only use single lines drawing characters ( which work fine ) for now as a work around. Here is my /etc/default/console-setup
Code:
# Change to "yes" and setupcon will explain what is being doing
VERBOSE_OUTPUT="no"
# Setup these consoles. Most people do not need to change this.
ACTIVE_CONSOLES="/dev/tty[1-6]"

The numbers in the FONTFACE show the size of the font matrix. For example Lat2-Terminus20x10.psf is a font for codeset Lat2 with size of the font matrix 10x20 (i.e. 10 columns and 20 rows). If the number of columns is 8 then only the number of rows is specified. For example the font matrix of Armenian-Fixed15.psf has size 8x15.
In text video mode or if you use the RadeonFB kernel module only fonts whose font matrix has 8 columns can be used (that is the size should be a simple NUMBER rather than a NUMBERxNUMBER combination). The other fonts can be used only with framebuffer video modes and with the package 'kbd'. The console package 'console-tools' can not be used
with such fonts.
THE TERMINUS FONT:
The aim of the Terminus font is to reduce the eyes-fatigue when one has to read a lot. Currently this font supports only the Latin, the Cyrillic and the Greek scripts (the Lat15, Lat2, Lat7, CyrAsia, CyrKoi, CyrSlav, Greek, Uni2 and Uni3 codesets). The fonts with font face TerminusBold and size 14 or 16 are optimized for 8 pixels width glyph matrix (in most cases this means framebuffer). The fonts with font face TerminusBoldVGA and size 14 or 16 are optimized for 9 pixels width glyph matrix and can not be used with
framebuffer video modes.
The fonts with font face Terminus and size 14 or 16 can be used both with 8 and 9 pixels width glyph matrix. In the regular text video modes the width of the glyph matrix is 9
pixels. If you use the package svgatextmode then the width is 8 or 9 pixels and you probably know it. The Terminus font in this version of console-setup is version 4.26.

This is a C++ program I wrote years ago that has been chugging along fine with no problems until I recently upgraded from Slackware 13.0 to 13.1. Suddenly the process dies with a segfault. I recompiled against the new libraries and still no luck. This is the offending bit of code:
Code:
int comm_handler::transmit(const byte* out, size_t len) {
size_t written = 0;
ssize_t count;
int fail = FALSE;
[code]....
When it is called with out = "ATH0 " and len = 5, I get a segfault. When I call it with out = "ATH0 " (note trailing space), it goes through. Unfortunately I need a carriage return at the end or the modem doesn't process the command.
