[gentoo-user] sys-power/upower with systemd
I think I had first misinterpreted the news msg, but want to be sure I do understand it correctly now. The message ends with All non-systemd users are recommended to choose between: # emerge --oneshot --noreplace 'sys-power/upower-pm-utils' or # emerge --oneshot --noreplace '>=sys-power/upower-0.99.0' However, all systemd users are recommended to stay with sys-power/upower. I first read "stay with sys-power/upower" to mean systemd users should NOT do any of the two options for non-systemd users and let portage "do its thing". However, portage want to replace upower with upower-pm-utils, which I am pretty sure is not intended for systemd users. Is the proper reading of the news message, that the systemd users should use the second option available for non-systemd users? Specifically am I to execute # emerge --oneshot --noreplace '>=sys-power/upower-0.99.0' ? thanks in advance, allan

Here is more detail on my approach... 1) Generate a random 8-letter name for a directory with the command head /dev/urandom | tr -d -c a-z | tail -c 8 Let's say you got "cjyqsiqd" (without the quotes). 2) mkdir ~/.mozilla/firefox/cjyqsiqd (or whatever 8-character string you got) 3) Create directories for a template profile, plus the profiles you want to use. I'll call them "profile1", "profile2", etc, but in real life, you'll want more descriptive names. mkdir ~/.mozilla/firefox/cjyqsiqd/template mkdir ~/.mozilla/firefox/cjyqsiqd/profile1 mkdir ~/.mozilla/firefox/cjyqsiqd/profile2 mkdir ~/.mozilla/firefox/cjyqsiqd/profile3 ... mkdir ~/.mozilla/firefox/cjyqsiqd/profilen 4) Create the profiles starting with the template profile. Note that there is a good reason for navigating into the profile dirs. It will become obvious later. The command is... firefox -new-instance -ProfileManager Create Profile Next Enter new profile name: (more intuitive if it matches the directory name) Choose Folder (Navigate into the corresponding folder before clicking Open) Open Exit Rinse lather repeat for all the other profiles you'll want. 5) For the next step do not delete the template dir, but delete all the other profile dirs you've just created. No, this is not a joke. cd ~/.mozilla/firefox/cjyqsiqd/ rm -rf profile1 profile2 profile3 ... profilen 6) Launch firefox with the template profile... firefox -new-instance -P template ...and tweak it to your heart's content, keeping in mind what options your profiles will need. Install extensions, set font sizes, your favourite behaviours, tweak the menu bars, set cookie options, etc. And make sure to set the browser to open to a home page (more on that later). When you're finished, exit Firefox. 7) Copy your template directory to replace the profile directories you deleted in step 5. This is a lot easier than doing the same changes in several directories. The names will be different depending on what did in step 3. cd ~/.mozilla/firefox/cjyqsiqd/ cp -r template profile1 cp -r template profile2 cp -r template profile3 ... cp -r template profilen 8) Open the profiles and do the final customizations for each profile separately. The command is firefox -new-instance -P profilename The customizing includes stuff like which cookie domain(s) to accept and which page(s) to open on startup. And yes, you can get Firefox to open multiple tabs on startup. When entering the homepage to open, separate the pages with pipe signs " | ", e.g... http://foo.com | http://bar.com | ftp://bad.example.com/data.txt > Note, you will also need to remove any flash cookies (LSOs) which > sit in your ~/ and are not deleted, unless you have installed the > Better Privacy addon. For a more pedestrian approach: > > rm -Rf .macromedia/Flash_Player/* There also seems to be ~/.adobe directory. What I do is to create *FILES* (yes) like so... touch ~/.adobe touch ~/.macromedia This blocks the creation of directories by that name. Some idiot sites will refuse to play videos in that situation. I click on the Flash button, and the video displays something like "Error #2046". I have a workaround for that, namely a script ~/bin/killflash like so... #!/bin/bash rm -rf ~/.adobe rm -rf ~/.macromedia sleep 20 rm -rf ~/.adobe touch ~/.adobe rm -rf ~/.macromedia touch ~/.macromedia I launch killflash in an xterm, and then click on the video to play. Note that the video only has to start within the 20-second window. The way that linux works, you can delete a file, but any app that has it open will continue to see it, even though no other apps can. As soon as the last filehandle to the file is closed, its space is finally released. -- Walter Dnes I don't run "desktop environments"; I run useful applications

Taking this a step further I create additional one-off profile directories in /tmp, which are deleted when I reboot (this is a laptop), which ensures that tracing between sites does not happen.

I have sometimes wanted to use the same bookmarks file/db for all of my web browesers I have compiled on a given system. For seamonkey and firefox that should not be too difficult as they have the same file structure in your ~/.mozilla/ directory structures. So just point them (sym link) to the same file should do the trick, as long as they are both not running at the same time. The tricks I never got around to figuring out was how to use the same bookmarks, simultaneously with both running that the same time, as well as other differnt web browsers, such as Opera etc etc. Suggestions and ideas are most welcome on this scenario.

From the perspective of having to install and use something that I hitherto never needed, it involves more configuration than I would like to bother myself with. A moot point I know, since additional functionality brings with it additional configuration options. Anyway, I have now installed PA and am using it, so it can't have been all that complicated. ;p -- Regards, Mick

O_o The switch was mostly successful, except for: After a reboot all worked fine and the pulseaudio migration appeared to be uneventful. The morning after things went sideways. The HDMI sound device was selected as the default audio and not analogue sound was available. For some reason the default beep was loud enough to wake up the neighbours! PCM, headphones and other controls had disappeared and some new monitor-* controls were available. This was fixed by adding: load-module module-alsa-sink device=hw:0,0 load-module module-alsa-source device=hw:1,0 in /etc/pulse/default.pa I have not yet tried the microphone in Skype to see if the above combo is correct.

I unmute the second headphone jack and raise the volume setting - sound is back. I stop and then start again mplayer - no sound. I unmute the second headphone jack - sound is back. and so on. I cannot understand why the second jack is muted. The first jack stays unmuted in each case. -- Regards, Mick

Also, if you close one and it doesn't die correctly, you can use this little trick, as a script in my case, to find the process for each one that is running. ls -al /home//.mozilla/firefox/*/lock For example, on mine it returns this, name somewhat edited: root@fireball / # /root/firefox ls -al /home/dale/.mozilla/firefox/*/lock lrwxrwxrwx 1 dale users 16 Jun 22 22:57 /home/dale/.mozilla/firefox/4p9tgzd5.MOD/lock -> 127.0.0.1:+28060 lrwxrwxrwx 1 dale users 16 Jun 22 22:53 /home/dale/.mozilla/firefox/ar78vn2c.default/lock -> 127.0.0.1:+27753 lrwxrwxrwx 1 dale users 16 Jun 22 23:58 /home/dale/.mozilla/firefox/hmnj07pv.Greet staff/lock -> 127.0.0.1:+31137 root@fireball / # Notice the process number on the end? If say I close the default but it doesn't die as it should, I can do this: kill 27753 The other processes are still running. Also, if it is dead but it didn't remove the lock file, just use rm instead of ls and remove the options of course. Hope that helps you as much as it did me. ;-) Dale :-) :-) -- I am only responsible for what I said ... Not for what you understood or how you interpreted my words!
