Hi all ;-)

I just had a bug with vlc(Segmentation fault) on Blag/Freedora-Libre-Kernel 20 as describred here:
http://forums.fedoraforum.org/showthread.php?t=297566
vlc is now working after:

Code:
vlc -vv --avcodec-hw none



this disables hardware acceleration

but mainly i found myself after
http://valgrind.org/
Quote:
Valgrind is an instrumentation framework for building dynamic analysis tools. There are Valgrind tools that can automatically detect many memory management and threading bugs, and profile your programs in detail. You can also use Valgrind to build new tools.


Code:
valgrind /usr/bin/vlc


not being able to scroll all the way up to the initials commands.Maybe as i issued quite a few commands the Terminal became saturated?
several commands with hundreds of lines as result(should i quit on each hight-verbose-result and relog after having copied and pasted of course the result?)
just the $ vlc -vvv /home/linuxlibre/Téléchargements/'Peuterey Integral Ridge.mp4' gave a result of 182 lines!
My question is as i have been encouraged to file a bug report after installing

Code:
# debuginfo-install vlc-core-2.1.4-1.fc20.x86_64

(not installed yet)
https://fedoraproject.org/wiki/StackTraces

Is there a way scrolling up:ie giving maximum verbose in the terminal(i guess i have a 500 line mx capacity but the info ,rushs so fast and is so "quantitative that't it's hard to know) if i encounter such situation again.
i have tried:

Code:
 $history

but that will show just the later commands:

161 vlc -vvv /home/linuxlibre/Téléchargements/'Peuterey Integral Ridge.mp4'
176 yum install valgrind
177 su -
178 valgrind VLC
179 valgrind vlc
180 valgrind -v vlc
181 rpm --checksig ffmpeg
182 rpm --checsig ffmpeg
183 rpm --checksig --nogpg ffmpeg
184 rpm --checksig vlc
185 yum remove ffmpeg(was re_installed after)
186 su -
187 valgrind /usr/bin/vlc
188 vlc -I skins2
189 cvlc FILE
190 cvlc 'Peuterey Integral Ridge'
191 svlc/home/linuxlibre/Téléchargements/'Peuterey Integral Ridge.mp4'
192 vlc -vv --avcodec-hw none
193 exit
194 history

terminfo - terminal capability data base

http://linuxmanpages.net/manpages/fedor ... nfo.5.html

Suffix Meaning Example
-nn Number of lines on the screen aaa-60
-np Number of pages of memory c100-4p
-am With automargins (usually the default) vt100-aa


this is too quite complicated i don't know how to even access to the info which would inform me on my max-lines-in terminal.

Be grateful for any suggestions ;-)

Don't understand anything. Mine works fine on Hatrack 20 and freed-ora 20!
For the terminal: I think you use your distro in French; so open your terminal and then: Edition-->Préférences du profil-->Défilement and you configure as you like it.

Thanks
Junichirô ;-)
I don't understand either why all was working fine on Freedora19 and not
on F20.Vlc works's fine on GdNewHat'Hatrack'
The explanations i've been given are:

Quote:
The problem seems to be with the interface cairo is breaking down
there for some reason and you using another one the svlc shows it
works...&...It is a bug, VLC hardware acceleration is interfering
with the desktop compositor that is why it crashes or so I think it is,
seriously don't take my word for it, test everything and see it for
yourself.


As far as the Terminal that's exactly what i was looking for ;-) i got
mislead into
terminfo - terminal capability data base
Terminal > Edit > Preferences > Scrollback was on 1000
Lines/have put it 2500...
after issuing several commands i guess i was above the capacity.Thus not
being able to scrollback to the 1st command.

It seems there are lots of problem with Fedora 20 and DVDs reading: http://forums.fedora-fr.org/viewtopic.php?pid=534668#p534668

By chance I don't have. But remember having some with GdNewHat 19. But I think it came from Gnome 3 and acceleration problems. Have not with mate!
