User Submitted Tutorials / Re: Fix screen tearing on Intel graphics chips
« on: January 19, 2017, 08:01:35 pm »
Thanks for this tweak.
I wasn't aware of the problem.
This solves it completely.
Using Xubuntu 16.10 with Xfce4, FYI.

I appreciate these suggestions to disable the caps_lock toggle,
but none of them worked for me using a Dell Inspiron 1545 laptop and Peppermint 7.

What did work was adding, or adding-to, the file ~/.config/lxsession/Peppermint/autostart
a command somewht like one suggested early in guyboertje's initial post:
Code: [Select]
setxkbmap -option ctrl:nocaps

Networking / Re: Updated Broadcom wl wifi driver.
« on: August 17, 2016, 05:10:16 pm »
For reference, I am using
Synaptic package broadcom-sta-dkms version to install
    the 64-bit wl driver, broadcom-sta-dkms(amd64) in Peppermint 7.

Using PCNetSpec's lsmod command, I get the following:
Code: [Select]
peppermint@peppermint ~ $ lsmod  | grep "brcmsmac\|b43\|ssb\|bcma\|wl\|b44"
wl                   6447104  0
cfg80211              565248  1 wl
peppermint@peppermint ~ $

bcmwl-kernel-source will install an earlier version of the STA-mode wl driver,
version '248 rather than '271.

I have experienced good throughput using Peppermint 7 and version 271 and
similar improvement over b43 results using Lubuntu 16.10-alpha and bcmwl-kernel-source and
version 248. In both cases I just used Synaptic and didn’t try to help it
with any blacklisting.

@ Bigouef
My advice is not to diddle with a well-working system, but rather give this
idea a try-out on a LiveUSB install. UUI makes it very easy to make a LiveUSB
with persistence directly from an iso and 16 Gb USB3 Cruzers are very cheap.

I have no issue with all your suggestions here, I was perhaps extremely lucky using Synaptic
and having such good luck with so little effort in this case.

Hello, Bigouef.

Sorry to be so late with this response.
Glad you find some interest in my original post about replacing b43 with wl.

FYI, I've always used the broadcom-sta-dkms offering in Synaptic to install the updated wl.
I've done this successfully with a number of other current Linux offerings.
I haven't blacklisted anything, myself.

Anxious to hear how this turns out for you.


Just in case you're still interested, here's the tutorial for swapping nemo for pcmanfm,4063.0.html
Thanks for the note.
I hadn't deleted nemo, luckily, or I would have had a cruel surprise, apparently.
My impression was that PCManFM was a more complex device than nemo, apparently not?
Anyway, I just am more familiar with some utilities than others.

FYI, on another matter, I am researching the snap topic and will start another thread
on that when I have something coherent to offer.

Best Regards.

Hello Slim.

Thanks for your comments.
You could be right on this, of course.
Here's where I think this might have some appeal:

PM7 has a neat, small iso slightly less than 1 Gb.
If you want to add LibreOffice to that, this is another 1015 Mb in persistence.
If that were instead available for ~287 Mb squash-file, that would achieve
the effect of re-mastering without all the hassle, not to mention all the
necessary real-estate used in re-mmastering.

The mechanism of snaps is quite similar to using Synaptic, only the terms
used are different.

Also FYI, PM7 Synaptic already has the snap daemon, snapd available to tinker-
with. I've added snapd to my PM7 LiveUSB and I'm digging into the following
references if you become interested.

Best Regards.

See if
Code: [Select]
sudo apt-get cleangets you any space back
This looks like a good idea, might recover as much persisence as a third of the material I've added.
This also prompted me to see if anyone on the forum is using 'snaps' as an alternative to remastering.
I don't get any results back from using the forum search using snaps as a keyword.  Any thoughts on snaps?

Thanks for your responses

I am assuming, but I have not proven this, but I would be surprised if
Gnumeric is a smaller program that it will properly handle
all the various subtleties of a larger and more complex program.

What I require is an application program that will allow me to contiuously
change the structure and parameters of a relatively complex personal
spreadsheet. I don't want to start all over re-programming the spreadsheet
to suit a new application program unless I absolutely must.

@murramint & PCNetSpec
My problem, which has gone away now, was the inability of LibreOffice
by itself to recognize and load-in mounted media. LO couldn't see my
Windows partition if I mounted it, nor any attached and mounted usbs.
Some dependency or dependencies beyond base, calc & rate were required,
I don't know which, specifically, but I would bet it's fewer than the
whole gamut contained in LO metapackage.

The liberties I have taken in adding and replacing programs in Peppermint 7
are beginning to pinch, I must admit, I set aside 2.4 Gb for persistence
and with all my tweaking, I'm up to 2.0 Gb now. I'm not a practiced hand
at  re-mastering.

Thank you both for your responses.

I expect using the metapackage is overkill in this situation. But there are
so many other packages that are brought-in by metapackage that it might take
some time to discover just which one or two dependencies might solve my minor
file management quibble.

I also expect my LiveUSB usage of Peppermint may be of some annoyance if the
main thrust of Peppermint is intended more in support of ChromeBooks and
Site Specific Browser applications. Peppermint does adapt itself well to my
uses, it should be noted and my quibbles are minor and ideosyncratic 

I have some previous programming efforts already invested in LibreOffice spread-
sheets and text documents. Almost the same problem as with proprietary, in that
past efforts get locked in by their unique formats. Otherwise Abiword and/or
Gnumeric would likely serve as well or better on new projects.

@ PCNetSpec
What I was trying to avoid was using another program to start LibreOffice.
I was dissatisfied in requiring any file manager to do what I expected LO
to do for itself. I do slightly prefer either Thunar or PCManFM to nemo, but
that was not my concern in this posting.

Here's a remedy; spend 140 Mb and install the LibreOffice metapackage.

I thought using base, calc & write would suffice to give me all the LO
capability I needed. Apparently not. Having installed the metapackage,
my complaints about the built-in file mgr have gone away.

Not likely this is the most efficient solution.

Software & Applications / Locating local media off-line with LibreOffice
« on: August 04, 2016, 05:20:06 pm »
I have LibreOffice installed in my Peppermint7 LiveUSB on my laptop.
I have LO spreadsheet files on another data USB mounted on my laptop.
I can locate, locate, work on these, and ultimately save them back to the
data USB.

What is unusual in this instance is that I cannot locate the data USB using
the file management system within LibreOffice itself, nor can I figure out
how to adjust LibreOffice to have this capability which I normal have and
expect in similar Linux LiveUSB configurations.

In this regard, the LO file manager seems to expect (only?) remote file
services ranging from 'Google drive' to 'Windows share'. I do not intend to
operate 'in the cloud', just from within the laptop itself. I admire this
new SSB feature, but I don't feel the need for it yet.

I would appreciate some hints on how to adjust things in the old-fashioned way,
and I don't know where to start. TIA

User Submitted Tutorials / Re-starting the x-server.

Re-starting the x-server.

Sometimes the x-server gets all confused and needs to be reset.
Or maybe you've changed something like .bashrc and it needs to be reset
to make changes effective.

If x is not working right but you can still access a terminal in some form,
a simple command line will restart x for you. Speaking from Peppermint 7
experience, of course, with Systemd a part of your Linux system.

peppermint@peppermint ~ $ alias restartx
alias restartx='sudo systemctl restart lightdm.service'

Doing 'restartx' in a terminal is much less of a hassle than logging out
and logging back in without a full restart.

You can define 'restartx' in the current session, but it won't be there on re-boot
unless you also add it to your (hidden) ~.bashrc file.

If x is so hung-up that you can't access a terminal AND you can't even log out,
then using Ctrl-Alt-PrntScrn R E I S U B is preferable to using the power button
to shut-down, but that's another story; google REISUB for many accounts on this
other magic trick. 

Thanks for this suggestion.
Thanks also for the spoiler explanation.

Thanks for your comment.

I am pointing out that the 'integrity check' menu choice checks 360 md5sums
but merely ignores failed md5sum checks. My guess is it certainly must do
something more significant if the squash file fails. Some Ubuntu 10.04
derivatives whiz through all the md5s and don't even call out failed md5s,
if any.

I would think some users might wonder why some of these md5sums may be wrong.
Six or seven of my md5sum fails are caused by initramfs ops in getting my wifi
driver shifted over to something better than the default. That might not be so
obvious to some users.

Networking / Re: Updated Broadcom wl wifi driver.
« on: July 24, 2016, 01:22:18 pm »
Thanks for your comment.

Having used both b43 and wl interchangeably for years, this last Broadcom update
changes the ballgame for this Dell computer by about a factor of two in speed.
Since Peppermint does a perfect default install of b43, I think it is news-worthy
that struggling to bring in the new wl Version '271 is worth the effort for
Dell 1545 Inspirons and possibly others.

 I first noticed this on PCLinuxOS, then Peppermint. I think the change may be using
some 64-bit magic where earlier drivers may have been only 32-bit. It used to be one-
size-fits-all; now there's a 32- or 64-bit choice.

For those more technically gifted than I, there is a Broadcom reference that
might help explain what's new here. Find this at
The README file at the bottom of that page is the place to start.
