How to see terminal screen msgs

Post#1 by Ed_P » 27 Dec 2013, 22:28

When I shutdown the screen is always full of text. How do I view this text prior to shutting down?? The only way I've found is with a camera and as you can see it's not a good option.

I can see some kind of a Fatal error msg near the bottom which I would like to know more about also.

Hi Ed!

See if the recommandation of fanthom does apply to you:
viewtopic.php?f=48&t=2851&hilit=+save+c ... der#p19616
boot to text mode with 'debug' cheatcode enabled and use shift+PgUp/PgDown to scroll the screen
In my menu.lst I have:

Code: Select all

title porteus v2_64 on sda5 64bit_v21   KDE TEXT MODE DEBUG
root (hd0,4)
kernel /64bit_v21/boot/syslinux/vmlinuz from=/dev/sda5/64bit_v21 debug changes=EXIT:/64bit_v21/kde load=kde.xzm extramod=/mnt/sda5/64bit_v21/porteus/modules-super/ login=root
initrd /64bit_v21/boot/syslinux/initrd.xz 3
boot

À la prochaine. 8)

The debug cheatcode is only useful for booting. Porteus is so fast at shutting down (a tribute to fanthom) that the error messages spat out don't have time to hit the floor before the screen goes out.

Just a thought.

1) Boot into text mode (with changes= cheatcode functioning).
2) type: startx 2> /home/guest/mylog.log

Now all X errors should be redirected to your new log file. Because you are saving changes this file should persist the next boot and you can read it.

PS: As stated in another thread, these errors are from qxkb and are nothing to worry about. I am familiar with them and recognized them even in your very fuzzy photograph. :ROFL:

if you want to be able to read messages during shutdown then please edit /mnt/live/cleanup script and add 'read' command somewhere at the end of it but before 'reboot/poweroff' commands. now you will be able to read everything and shutting down wont continue until you press enter.

also - if you want to get a shell then add 'sh' command to the cleanup script and press 'ctrl+D' to continue shutting down.
Please add [Solved] to your thread title if the solution was found.

Wow!! Thanks guys for all the suggestions. :good:

While I am somewhat concerned about the Fatal error msg I'm also concerned why there are so many other msgs seemingly related to what I have been doing in GUI mode. All this text msg writing has got to have an impact on performance. I don't recall this volume of text msgs in prior releases. Are they caused by the qxkb problem or is that just related to the Fatal error seen in the fuzzy photograph? And if they are caused by the qxkb problem will there be a fix anytime soon?

Most of the messages are normal reports from qxkb. The only fatal errors are from qxkb and qlipper upon shutdown.. Probably from having the service terminated during shutdown. There should be no impact on performance or usage during your session. I'll look into how to kill them gracefully.

Actually the msgs I'm more concerned about are the ones shown in this blurry photo.

It seems that Porteus is erring out constantly.

Is there a cheatcode to do that? I'll check myself later if you're busy.

At the menu screen select the 'textmode' and then hit the TAB button. You can add your changes=/path/to/changes in there. Or edit the porteus.cfg file if you are not botting from an ISO.

These error messages look like they are coming from the gtk theme. I am using the latest oxygen theme for razor but i have noticed other bugs in it. For example, open geany (development program) and then minimize it and then in a terminal enter: top to see the process usage and watch the CPU start to fry! (hit 'q' to exit from top)

This doesn't happen with other themes. I might look at moving from oxygen ... but it looks so nice.

I don't have a menu when I boot Porteus, I go directly to startx with 2.1 regardless of which boot option I choose.

Code: Select all

With changes= cheatcode
kernel /boot/syslinux/vmlinuz    from=/ISOs/Porteus-RazorQT-v2.1-x86_64.iso changes=EXIT:/porteussave.dat    
initrd /boot/syslinux/initrd.xz

With extramod= cheatcode
kernel /boot/syslinux/vmlinuz    from=/ISOs/Porteus-RazorQT-v2.1-x86_64.iso extramod=/mnt/sda6/porteusmodules
initrd /boot/syslinux/initrd.xz

Fresh mode
kernel /boot/syslinux/vmlinuz    from=/ISOs/Porteus-RazorQT-v2.1-x86_64.iso   
initrd /boot/syslinux/initrd.xz
With the prior release I used the cheatcode autoexec to run startx when booting.

BTW Is the password for guest guest?

I like RazorQT's oxygen also.

Ok. I suspect the noauto cheatcode will do that for me.

And I have found that once booted ctrl+alt+F2 will allow me to resignon as guest and issue the startx command you showed. My next terminal msgs posting should be considerably clearer. :wink:

Just following the advice given here: viewtopic.php?f=81&t=2212&start=15#p18076

And startx closes it also. :)

@phhpro

While I am sure you know much more about Linux than I do, I do know what works, or not, on my system.

I boot to the RazorQT desktop.
I press ctrl+alt+f7 and nothing happens.
I press ctrl+alt+f2 and I exit the desktop and enter a terminal window.
I enter root, toor and startx and I am back at the desktop.
I press ctrl+alt+f7 and nothing happens.

That to me indicates that startx ends the terminal mode since ctrl+alt+f7 doesn't return me to the terminal window.

Things may work differently for you with your desktop system.

ctrl+alt+backspace is an interesting option. It signs me off without closing the desktop window. Thanks.
Ed
