  • Strange behaviour when screencasting

    - by Luis Alvarado
    Since an update I did yesterday I am not able to screencast any video using Kazam, Recordmydesktop or even ffmpeg/aviconv. After the upgrade to some libraries (A normal update that showed in Update manager) the problem was this: When doing the screencast, scrolling inside an Apps window like Firefox, Chrome or Gedit is not shown. The video only shows the last image it recognized before I started scrolling. For example with Gedit, I have a lot of text on it and when I start to scroll down, the video only shows what I had in the beginning while I listen to myself talk about what is in the rest of the file (Which is not shown in the video). When opening a window, for example again Gedit or Chrome it might not show in the video, it will just show the desktop without the window opened. I do not see any error with dmesg, syslog or others. What can I check to debug this problem?

  • Installed Ubuntu on a macbook pro and am running into errors with internet

    - by user209270
    I recently installed Ubuntu (64 bit, 12.04) on a mid-2012 Macbook Pro, and I've been having some really annoying issues. Chief among them is that my wireless doesnt seem to function properly. I've installed Ubuntu on this mac before, and again this time the drivers for the wireless card were missing. I, using something along the lines of sudo su apt-get update apt-get upgrade apt-get b43-fwcutter firmware-b43-installer A new problem I've been experiencing however is that none of the networks available in my home show up. I've been able to connect theto themm by going into "Connect to hidden networks" and typing in the network name and password, but when I restart the computer my network (let's just name it "Network1"), doesnt show up. I tried going into "Edit Connections" and it shows up in the wireless tab, but it is never connected to automatically or shows up in the drop-down menu. Any help?

  • Unable to install MS Office, wine1.7, and getting updates

    - by spirit
    I am a new ubuntu user, just installed 12.04 LTS. Learned a lot from ubuntu users suggestions on the webs. I am a student and frequent user of MS office. However, I am unable to install MS Office as failing to get updates plus installing wine1.7. sudo apt-get update shows something about unable to connect archive.ubuntu.com and some files failed to download, they have been ignored or older ones have been used instead. sudo apt-get install wine1.7 shows something about unmet dependencies and broken packages.

  • 13.10 Desktop - Stop Suspension on Lid Closure

    - by bpmitche
    I'm having a problem with power management settings on my ASUS K52-F Laptop. Upgraded from 13.04 to 13.10 earlier today; closing the laptop lid puts the laptop into suspension (even on AC Power - tried fixing it in gnome power settings, tried fixing it in Cinnamon power settings, tried changing it in DCONF-Editor, but no matter where I change the setting the laptop lid still suspends). After resuming from suspend, I restore to the gnome window/login manager (instead of Cinnamon login manager). Wifi doesn't reconnect, but the icon in Cinnamon shows that I'm connected. IFCONFIG shows that the interface is up and working normally, but still not reconnecting. ifconfig wlan0 down / up doesn't change anything. Any help would be greatly appreciated.

  • Does any CMS natively support something like aquaBrowser/Vufind

    - by nus
    What I'm looking for is to set up a CMS website with a tag cloud/search system where when you click a tag it shows as a search filter, and you get a new tag cloud which only shows tags from the articles that have the primary tag. This should let the user easily include or exclude tags from the search. Also i would like to let the user filter on publication date by using a slider... Check this for an example of how aquabrowser does this (just search for something and play with the tag cloud): http://kidscatalog.columbuslibrary.org It's not perfectly what I want and I don't want to use flash, but I like the concept alot. If something like this does not exist and i might have to code it myself, which cms is most recommended (eg easy to extend, already has tag clouds and search filters,...)

  • 12.04 gnome shell broken after updates

    - by nat
    I'm running Ubuntu 12.04, and using gnome shell. I've had my machine running for the last few days, and I've been installing updates as the update manager bugs me. I just rebooted, and now gnome won't start. I can use gnome classic and unity, but gnome 3 isn't working at all. When I log in, the screen is black for maybe 20 seconds, but the cursor shows. Then, my wallpaper, but nothing else shows up. I can get a terminal with ctrl+alt+t, and I tried to run gnome-shell, but it segfaulted.

  • ATI ES1000 graphic card

    - by Jorge Biurrun
    I am installing Ubuntu 12.04 on an IBM x3250 M2 server, It has an ATI ES1000 with no acceleration (that does not bother me, we don't need it), we use it to connect remotely via FreeNX. FreeNX works fine, (except than in Windows 7 machines NX Client shows only icons and no text ?!) but the only resolution I can get in the monitor directly attached to the server is 800x600. The display manager also shows me two monitors!, the real one and one IBM 15". Which driver should I install?. It seems that the ATI driver that comes with Ubuntu does not work properly. Any help will be apreciated. Thanks in advance. j&b

  • git local master branch stopped tracking remotes/origin/master, can't push

    - by Paul Smith
    Just when I thought I'd got the hang of the git checkout -b newbranch - commit/commit/commit - git checkout master - git merge newbranch - git rebase -i master - git push workflow in git, something blew up, and I can't see any reason for it. Here's the general workflow, which has worked for me in the past: # make sure I'm up to date on master: $ git checkout master $ git pull # k, no conflicts # start my new feature $ git checkout -b FEATURE9 # master @ 2f93e34 Switched to a new branch 'FEATURE9' ... work, commit, work, commit, work, commit... $ git commit -a $ git checkout master $ git merge FEATURE9 $ git rebase -i master # squash some of the FEATURE9 ugliness Ok so far; now what I expect to see -- and normally do see -- is this: $ git status # On branch master # Your branch is ahead of 'origin/master' by 1 commit. # nothing to commit (working directory clean) But instead, I only see "nothing to commit (working directory clean)", no "Your branch is ahead of 'origin/master' by 1 commit.", and git pull shows this weirdness: $ git pull From . # unexpected * branch master -> FETCH_HEAD # unexpected Already up-to-date. # expected And git branch -a -v shows this: $ git branch -a -v FEATURE9 3eaf059 started feature 9 * master 3eaf059 started feature 9 remotes/origin/HEAD -> origin/master remotes/origin/master 2f93e34 some boring previous commit # should=3eaf059 git branch clearly shows that I'm currently on * master, and git log clearly shows that master (local) is at 3eaf059, while remotes/origin/HEAD - remotes/origin/master is stuck back at the fork. Ideally I'd like to know the semantics of how I might have gotten into this, but I would settle for a way to get my working copy tracking the remote master again & get the two back in sync without losing history. Thanks! (Note: I re-cloned the repo in a new directory and manually re-applied the changes, and everything worked fine, but I don't want that to be the standard workaround.) Addendum: The title says "can't push", but there's no error message. I just get the "already up to date" response even though git branch -a -v shows that local master is ahead of /remotes/origin/master. Here's the output from git pull and git remote -v, respectively: $ git pull From . * branch master -> FETCH_HEAD Already up-to-date. $ git remote -v origin [email protected]:proj.git (fetch) origin [email protected]:proj.git (push) Addendum 2: It looks as if my local master is configured to push to the remote, but not to pull from it. After doing for remote in 'git branch -r | grep -v master '; do git checkout --track $remote ; done, here's what I have. It seems I just need to get master pulling from remotes/origin/master again, no? $ git remote show origin * remote origin Fetch URL: [email protected]:proj.git Push URL: [email protected]:proj.git HEAD branch: master Remote branches: experiment_f tracked master tracked Local branches configured for 'git pull': experiment_f merges with remote experiment_f Local refs configured for 'git push': experiment_f pushes to experiment_f (up to date) master pushes to master (local out of date)

  • Query doesn't use a covering-index when applicable

    - by Dor
    I've downloaded the employees database and executed some queries for benchmarking purposes. Then I noticed that one query didn't use a covering index, although there was a corresponding index that I created earlier. Only when I added a FORCE INDEX clause to the query, it used a covering index. I've uploaded two files, one is the executed SQL queries and the other is the results. Can you tell why the query uses a covering-index only when a FORCE INDEX clause is added? The EXPLAIN shows that in both cases, the index dept_no_from_date_idx is being used anyway. To adapt myself to the standards of SO, I'm also writing the content of the two files here: The SQL queries: USE employees; /* Creating an index for an index-covered query */ CREATE INDEX dept_no_from_date_idx ON dept_emp (dept_no, from_date); /* Show `dept_emp` table structure, indexes and generic data */ SHOW TABLE STATUS LIKE "dept_emp"; DESCRIBE dept_emp; SHOW KEYS IN dept_emp; /* The EXPLAIN shows that the subquery doesn't use a covering-index */ EXPLAIN SELECT SQL_NO_CACHE * FROM dept_emp INNER JOIN ( /* The subquery should use a covering index, but isn't */ SELECT SQL_NO_CACHE emp_no, dept_no FROM dept_emp WHERE dept_no="d001" ORDER BY from_date DESC LIMIT 20000,50 ) AS `der` USING (`emp_no`, `dept_no`); /* The EXPLAIN shows that the subquery DOES use a covering-index, thanks to the FORCE INDEX clause */ EXPLAIN SELECT SQL_NO_CACHE * FROM dept_emp INNER JOIN ( /* The subquery use a covering index */ SELECT SQL_NO_CACHE emp_no, dept_no FROM dept_emp FORCE INDEX(dept_no_from_date_idx) WHERE dept_no="d001" ORDER BY from_date DESC LIMIT 20000,50 ) AS `der` USING (`emp_no`, `dept_no`); The results: -------------- /* Creating an index for an
