Re: Changing from Cinnamon to XFCE

Thanks Hoser Bob. I thought that might be a way of testing it "in production", so I could decide if I liked it or not, but if it's going to break my machine...... As a rule, it's not. There have been some problems in the past when mixing some Gnome forks, like Cinnamon or Mate, with Gnome (or each ...

Re: how to copy a mint installation?

You could probaby use gparted to copy the partitions on the USB to partitions on the HDD (assuming you have space there to create them). There are copy and paste options in the "partition" menu for gparted. Then you would just need to run sudo update grub on the Ubuntu Mate.

Re: How do you automatically login to Software Manager?

This issue is important to me because the Internet websites ASK FOR SO MANY PASSWORDS and Linux wants them as well! End the insanity now! BTW, a good idea for dealing with those internet passwords is to use a password manager, like lastpass. https://www.lastpass.com/ This is one of the biggest thin...

Re: How do you automatically login to Software Manager?

echo "$USER ALL=(ALL) NOPASSWD: /usr/bin/mintupdate, /usr/bin/mintinstall"|sudo bash -c "cat >> /etc/sudoers.d/mintupdate"
Not that this is a good idea, though.

Re: C++

Yes, the gcc compiler collection is capable of compiling C, C++, objective C, and more (including Ada and Fortran). But the default install in Mint is only set up for C. For languages other than C you really need to install the appropriate front end (Gobjc for objective C, Gnat for Ada, Gfortran for...

Good question. My understanding is grub currently defaults to using UUID when posible. I wonder though, when wouldn't it be possible?

Re: CPU usage seems high???

Another thing you can do to check what is using CPU time is to just open a terminal window and run the command top . That will give you a real time view of what's happening. I think the default view will have programs sorted by CPU use, but you can use the < > keys to change which column is sorted b...

Re: problem in installing python-numpy

Well what's the error this time?

It didn't give you an error for python-numpy. The error in the first post ocurred in configuring opensmtpd (which isn't related to python-numpy). Then that was successfully removed.

Re: stop mint from auto changing my monitor settings

Sounds like two different programs trying to manage the settings at the same time. Which version and release are you running, and what program are you using to change the settings (are you going to system-settings, display, for example)?

Re: SSH permissions on remote host

Don't think you want to use the command option. Duplicity will need to be able to run more than one command. There are ways you could put restrictions on the server end if you control the server, but if you only have a user account there, and no administrative access, I guess you can't worry about t...

Re: problem in installing python-numpy

Try purging and reinastalling opensmtpd.

Code: Select all

sudo apt-get purge opensmtpd
sudo apt-get install opensmtpd
Preview the purge command first by running with a -s before the package name, just to be sure this won't affect a lot of other packages.

Well it's been awhile since I messed with this, but it appears the sessions which appear on your display manager login screen are defined in /usr/share/xsessions/ , you can probably add sessions by adding a file there in similar format, like, for /usr/share/xsessions/openbox.desktop: [Desktop Entry]...

Re: Can't Boot

Sounds like boot loader (grub) didn't install properly. 1. First check firmware, see how it is set to boot, where it is looking for boot loader. 2. Boot with install disk or usb, and see if you can manually mount the drive which should have the linux installation. Just to see that it is installed th...

Re: How to swap physical hard disks (sda <-> sdb) with several Linux OSs installed

While switching disks from /dev/sda to /dev/sdb, etc., used to cause problems, I thought most thigns were using UUIDs now. So a first suggestion is to make sure everything on both disks, from /etc/fstab, to grub installations, is identifying all the partitions by UUID, not /dev.

Re: GRUB Causing Boot Problems

The computer firmware is often set up to try to boot first from an external drive, like a DVD, before booting from the hard drive. So that's why it's working with the DVD in there. So it sounds like Grub is incorrectly installed on your SDD. At least assuming you've actually removed the HDD, so it c...

Re: Why cant we emulate drivers?

The problem is that drivers typically have to interact with the hardware. That's the whole point of a driver. The point of an emulator is to run higher level programs that don't really have to interact directly with the hardware. So as long as something else is properly controlling the hardware, the...
