suddenly my laptop did not suspend when i closed the lid. i checked all settings of my linux mint 17 installation and all settings where correct. a quick search pointed me to http://askubuntu.com/questions/395428/laptop-does-not-suspend-when-lid-is-closed.
the solution for me was to edit
/etc/systemd/logind.conf, changing the option
suspend (valid options are
poweroff) and reboot the machine.
to globally toggle smart filters there is the key binding
"ALT" + "="
with version 1.0 there is also a per buffer key binding (according to this discussion) but it does not work with my current setup (using version 1.0.1)
"ALT" + "-"
i set up my fit-pc3 and had some trouble getting my xserver working .. here is how it went …
i was pleased to see a page in the wiki from compuLab but IMHO there are some points missing:
boot from usb flash drive
i changed the boot order in the bios (which you can enter via pressing “F2” during boot) but the screen was nothing but black. turned out that pressing “F1” randomly right after powering the machine it was booting from the usb flash drive.
linux mint 13 fails to boot
i also had to select “start in compatibility mode” to successfully boot the livecd
resolving xserver error – no screens found
after the installation finished the xserver would not start. some sites mentioned to simply update linux so i ran (after commenting “medibuntu” out in /etc/apt/sources.list)
sudo aptitude update
sudo aptitude upgrade
accepted any modified file to the maintainer’s version and restarted .. but nothing changed. so i follow the instructions from compuLab and installed the ati catalyst drivers using:
sudo aptitude install fglrx-updates xvba-va-driver vainfo
and restarted .. but still the xserver failed to start …
i finally cam across a forum post where the following command was mentioned
sudo aticonfig --initial
rebooted and the xserver was back again …
introduction – or why post so late?
as you will see in the script header comments i initially created it back in august 2012 .. as i saw the article on how to autorip dvds with windows on lifehacker i just had to reply …
i started writing this script because i wanted a ripping-solution which anybody could use. i did not want to write a howto for windows/linux but a solution that is truly auto-magic .. and then sends you an email when it’s done …
my approach for linux is a bash-script (now hosted on github) which can take one parameter for the dvd mount point. if no parameter is given it will go for “/dev/dvd”. it uses “mencoder” for the ripping, “mail” to send an email and “volname” to get the dvd volume name.
i then set this script to run as default action whenever a dvd video is inserted on my (atom) server, which is still running linux mint 9 with gnome. i did not have the time yet to set it up with LMDE but will post an update when i’ve done that.
unfortunately i could not find an easy way to embed the source .. therefore please go check it out over at github
gnome: set a script to be run whenever a dvd video is inserted
in nautilus selecet “edit > preferences”
then select the “Media” tab and set the script as default action for “DVD Video”
i bought an ebook reader (sony prs-t1 [which i rooted following this instructions]) and wanted to add all manuals of my house hold to it … so i could look up any setting quickly … so i downloaded the manual for my stereo system “TEAC TC-X350i” (from TEAC) and uploaded it to my ebook reader …
i had the idea that all manuals appear in the order %MANUFACTURER% %MODEL% …
i was confused that the manual on the ebook reader had the title “TC-X350I_OM_EF_…” and first thought of it beeing the filename .. but was wrong there … it turned out that this was some pdf-title …
i could not edit the manual as it was password protected … so i found the following solution to edit the pdf-title (and add other pdf properties):
run the following command to “print” a pdf named “temp.pdf” from the orginal pdf (named “original.pdf”) using ghostscript …
gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=temp.pdf -c .setpdfwrite -f original.pdf
install pdftk if you don’t have it installed:
sudo apt-get install pdftk
now run the follwing command to get a file (named “result.txt” containing all the pdf-properties aka metadata) …
pdftk temp.pdf dump_data output report.txt
open it in gedit or any other text editor and edit the line after “InfoKey: Title” (right after “InfoValue: “) … the following image shows my edited “result.txt” (i also added the author “TEAC” and a subject “Manual”) …
you then have to merge the new properties/metadata (the “result.txt”) to the “temp.pdf” using the following command which results in a new pdf “ebook_with_new_properties.pdf”:
pdftk temp.pdf update_info report.txt output ebook_with_new_properties.pdf
… that’s it .. you may delete the file “original.pdf” and “temp.pdf” now and use “ebook_with_new_properties.pdf” …
when trying to rip a video dvd using mencoder i got the error:
Please send bug report - no VTS_TMAPT ??
after a bit of googling it turnes out this is a well known bug .. and that it’s fixed in “libdvdread 4.1.3-10ubuntu3” so i double checked that the version i was using was the latest via aptitude …
as i did not get an update i searched for a new version and found this one for ubuntu precise:
so i just downloaded the .deb-file (to both my linux mint 10 and linux mint 9 boxes) and installed it with GDebi …
after this ripping and playback works again …
long time ago (very long) i set up a script which wrote the current date into a file and checked every hour whether the current date is different to that from the file .. and if so update dyndns …
pretty stupid .. right!
so i set up a new .. more reasonable one …
this one checks the current public ip address with the one set on dyndns ip (thanks!) ..
if it differs the dyndns ip is updated with the current public ip address …
you can find it (dyndnsCheckUpdate.sh) on github within my bash_scripts repository …
i now added this script as cron job to run every 15 minutes …
computers do behave strange sometimes …
my server would not mount any inserted media from the dvd drive any more .. for no reason it stopped …
finding this post i installed “cdde” and did a reboot .. now it works again …
sudo aptitude install cdde
when trying to use the zend debugger today it just would not work …
looking into “window > preferences > debug > installed debugger” it showed me that i have xdebug and zend debugger installed …
a page suggested to remove xdebug … but when running phpinfo() it did not show anything about xdebug .. so that could not be the problem …
another page suggested to look into the error.log from apache where i read:
[Zend Debugger] Debugger compile handler overriden, will not be active in this request
when searching for this i found another page pointed me into the right direction .. (this one: http://www.phil-taylor.com/2006/04/05/debugger-compile-handler-overriden-cannot-continue/)
phil mentions that the problem is with running both zend debugger and the ioncube loader .. made me remember that i did install the ioncube loader last week …
his suggestion to remove the following line from php.ini did not work for me …
therefore i removed the zend loader … will set it up again when needed …
to format a usb thumb drive you need a software called “gparted”.
to install it use the following command:
sudo aptitude install gparted
or you may also use the “Software Manager”,
search for “gparted” and install it.
after the installation run it either by starting it with the command
using the terminal or you may also find it in the mint menu listed in the group “Administration”
or just type “gparted” into the search box.
select the device you want to format from the dropdown list in the top right corner
when you made sure you have selected the correct device right-click the partition and select “Unmount”
then right-click the partition again and select the format you want the thumb drive to have from the sub-menu “Format to”
apply the changes by clicking on the ‘return’-button “Apply All Operations”
you have to confirm the operations to take effect
once the thumb drive is formatted you may close all windows and mount it by clicking on it in a nautilus window.
