Acer have made some alterations to the xfce4-panel, you probably noticed that you can’t right click and add launchers.
Edit: For anyone who came here to find out how to enable the “advanced menu” or XFCE menu on right click – Open your documents, click “File->Terminal” and type “xfce-setting-show” or just “xfce-se” then hit tab. Click “Desktop->Behaviour” and then tick “Show desktop menu on right click”.
I have a workaround but haven’t worked out why yet. Open a terminal (from a Thunar window if you haven’t enable the right click on the desktop). Now if you look in .config/xfce4/panel there is your standard xml file to layout the panel. If you alter this, on relaunching the panel it overwrites it with the default.
The odd thing is that the un-patched panel is still there, and works as normal (look in /usr/bin – there are two panels, one renamed xfce4-panel.old). Well for some reason that I haven’t fathomed, if you kill the running panel then alter the config then run xfce4-panel.old then restart it the xml config is not overwritten.
Currently in its fith revision, the system uses ten groupings but the 1908 translation’s first three classifications were: 0 to 20 – Idiot; 20 to 49 – Imbecile; 50 to 69 – Moron (the average IQ being around 100).
Also, believe it or not mental retardation and learning difficulties were referred to as the spectacularly offensive “Feeble Minded“.
People frequently ask for PDF versions of the Ubuntu System Help. We have a toolchain to build them but why not do it yourself?
This is true of any DocBook – dblatex is in the Ubuntu repositories and can transform DocBook in to many formats, the default being PDF.
Usually it is as simple as:
To generate filename.pdf. Most errors are easy to rectify because dblatex calls other tools and you can step through some (such as pdflatex).
However if you get an error along the lines of:
Overfull @hbox (20.76302pt too wide)
Well that is a bit of a pain. The prescribed wisdom is that something (usually a ulink) is just really too long, such as one of those really long URLs. In the case of DocBook, more often than not it’s a table that it just cannot render – so keep them simple!
There was a story posted on Slashdot today with regard to Bug #59695 (No link, intentionally). Apart from the fact that it was extremely poor form to post a link to Launchpad thus slashdotting a major bug tracking tool, this issue should be addressed quickly. Here is the bug report:
When switching to battery power, /etc/acpi/power.sh issues the command hdparm -B 1 to all block devices. This leads to extremely frequent load cycles. For example, my new thinkpad has already done well over 7000 load cycles — in only 100 hours. That’s at least one unloading per minute. Googling for “load unload cycles notebook OR laptop” shows that most laptop drives handle up to 600,000 such cycles. As these values clearly show, this issue is of high importance and should be fixed sooner rather than later.
Please see for yourself how often your drive is load cycling:
smartctl -d ata -a /dev/sda
(This command is for an SATA drive; you’ll need to install the smartmontools package first.)
See also http://paul.luon.net/journal/hacking/BrokenHDDs.html for a rather dramatic account of the effects the current default values may have.
Just in case the load/unload timeout depends on the specific laptop or disk model, here are my system specifications:
