Re: [PLUG] Parts shopping for new desktop

[Denis Heidtmann]

My previous desktop did not have front USB, so I had a short extension
cable bringing USB to the front.  Now that was 2.0, so I do not know if
something running at 10Gbps could tolerate such a solution, but I bet not.
I believe the reason for SATA Express is that it can accommodate higher
bandwidth.  And that bandwidth may be the reason Gen 2 it is relegated to
the back.

Just turn your machine around.  No need for those lights and buttons and
drives.

That may be a true prediction, but at the moment a SATA Express port
plus the device to mount in the front panel is the only way I can find
to get USB 3.1 Gen. 2 in the front of a desktop computer. I can find
plenty of motherboards that offer ports accessible in the back of the
computer, but I don't want to have to crawl around on the floor behind
the computer to plug in a portable drive.


How about a short usb extension cable to a usb on the back?

[PLUG] Parts shopping for new desktop

[John Jason Jordan]

For CPU I have settled on Intel i7 6700 or maybe 7700. The problems is
the motherboard because I insist on a USB 3.1 Gen. 2 port on the front
of the case, and that means an adapter like the following:

https://tinyurl.com/ycbkjf55

Unfortunately, that adapter requires a SATA Express connector, and I
can't find any motherboards with a SATA Express connector - lots of
regular SATA3 connectors, but no SATA Express connectors.

Shopping is a PITA. Any suggestions welcome!

Re: [PLUG] bash; anacron; wmctrl question

I have presently export DISPLAY=:0.  I do not know what the : means, and
why would you choose 1 rather than zero?  Note that presently the window

will be giving anacron an opportunity tomorrow with Wes' suggestion added.

Re: [PLUG] bash; anacron; wmctrl question

[Denis Heidtmann]

On the $DISPLAY variable, I  thought that is what export DISPLAY=:0  was
supposed to do.  It must be doing something, since the zenity window does
appear on my desktop.  It is just that the wmctrl -k does not seem to
work.  I will be trying Wes' suggestion tomorrow when anacron gets another
shot at it.

How might I enable logging, and which log files?

Re: [PLUG] bash; anacron; wmctrl question

[Tomas Kuchta]

Thinking little more about it - you might be able to get around the access
permissions - to display stuff on other user's screens by using xhost
command as part of user's default environment setup at login.

That however is breaking the security - you can imagine how the desktop
would look if random users can display stuff on your desktop. Beside
annoyances, I can imagine fake terminals, browsers, etc. and windows
covering whole screen without the closing button.

Re: [PLUG] bash; anacron; wmctrl question

[Tomas Kuchta]

I do not believe that you will be able to open graphical window using cron.
The best you can hope for is sending notifications or emails.

If you have the strength to continue with random experiments. Try: export
DISPLAY :1
In your script before launching the window. Although that will likely be
blocked because the executing user is different than the user owning the
graphical environment.

The only sure way, I can think of, would be to use existing or write own
notification system. This would run after login, by the user and accept
your notification messages for displaying.

Hope it helps, Tomas

Re: [PLUG] bash; anacron; wmctrl question

[Ali Corbin]

Another thing to try is to use the full path, in case the cron environment
doesn't include $PATH

try sudo wmctrl, the same way you're doing sudo zenity.
