Is my computer up to it?

Firefox with a few tabs open:
CPU maxing out? 70% RAM usage?
OK let's close Firefox:
Well, that dropped off!
And open Chrome:
CPU maxed out! Ram a little lower.
And let it settle down with a few tabs open:
OK, so I need to get scientific and open Firefox and Chrome with the same tabs open, but it seems that I've found the reason why my installation of Debian Buster (Testing as of time of writing) runs slow.

Back in 2015 when I bought this laptop, many reviews complained of mouse pointer lag - in Windows. An update seemed to fix it, but today it's back to the same condition- laggy mouse,and slow to open programs.

Have web browser become heavier? Has Debian become more bloated?

To me it looks like the web browsers are the culprit.


Things that are fixed in Debian Buster - Cancel print job in Gnome

In over two years of using Debian Stretch, I only encountered one bug. It wasn't possible to cancel a print job from the Printers dialogue in Gnome.

I am happy to report it is possible to cancel a print job from the Printers dialogue in Gnome in Buster.

Yay.

Here's hoping that Buster is as bug free. (Just to be clear, I'm testing the pre-release version, called, appropriately, Testing.)


Debian Buster preview

Two and a half years ago, I updated this computer to Debian Stretch while it was still Testing (the pre-release version) but in freeze (a stage when no new packages are added and bugs are ironed out).

Stretch has been a rock solid and reliable Debian release, both on this machine and on a later purchase, now the main family computer. But with a new version approaching, I always get the urge to try it out.

So, a few days ago, I updated the older computer, now rarely used, to Buster, which again is still strictly Testing but in freeze.

I'll make the same warning as I did at that time: Buster is still in Testing and can break. If it breaks, you get to keep the pieces.

So here is Debian Buster:
I have to confess I ditched the doggy wallpaper straight away and used the Moonlight wallpaper by Juliette Taka Belin.
Back in 2016 I wrote "The update was pleasantly painless with no issues". This time I wasn't quite so lucky. I ran out of disk space during the installation, and got this message:
No space left on device
I had tried to check if there was enough space for the upgrade using a command I found here (which suggested I had just barely enough). This computer has a separate root partition, given the default size of 10GB by the installer. This default size is really too small nowadays- at least for a Gnome install update.

Luckily I was able to run apt-get clean and apt-get autoclean to make enough space to finish the upgrade. Although I was given an error message before I could continue:
dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem 
When the upgrade completed, I rebooted the computer but it froze with just the cursor visible in the top left of the screen. That's my installation borked, I though, and went to bed.

However, the next morning I found I could boot into Rescue Mode and get a command prompt. I cleaned up the disc and found I could load the default installation. Hurrah!

Now I have Gnome running reasonably well. It does seem a bit slower than Stretch at times, despite the claim that Gnome 3.30 is lighter on resources. I may try a clean install at some point to see if that makes any improvement. This is a very low spec machine, it has to be said.

The most obvious change in is a switch from an icon grid to a sidebar list in Gnome settings. There are also minor changes to the file manager, and the addition of a Night Light mode, which changes the screen to a sepia tone, which apparently reduces eye stain at night.

One bug I have found so far is that the Gnome file manager does not create thumbnails for image files. This is a known bug, and quite easy to rectify by installing libgdk-pixbuf2.0-bin.

For me,  Stretch was a big improvement over Jessie. This update by comparison seems to add only minor improvements. My impressions so far are good, but I can live with my Stretch install on my main computer for a while. I will see what bugs get knocked out of Buster (a few fleas?) before updating it.

At least having an old laptop around I can scratch my update itch without inflicting those fleas on the family.

Debian Buster artwork proposals

Debian Buster approaches.

For those for whom that statement may be enigmatic, let me explain that Debian is a Linux distribution, and Buster is to be the name of the next version, Buster being a character from the movie Toy Story, after whose characters Debian versions are named.

With that out of the way, here are three of my favourite wallpapers from the Buster artwork proposals page on the Debian Wiki.

Moonlight, by Juliette Taka Belin

Synchronized Motions by Juliette Cougnoux

E-Legance by Foockinho

Debian users may notice that  Juliette Taka Belin's artwork was chosen for the two previous versions of Debian, Jessie and Stretch.

Moonlight is my favourite, as her proposal for Stretch was previously.

Good luck Juliette Taka Belin for three in a row!

Firefox 60 has remove title bar option

I've been trying out Firefox 60 in Debian Stretch. One of the new features I noticed is the ability to remove the title bar- something I have always considered a waste of space. You do this using the tick box at the bottom of the Customise page:
Firfox then looks like this:
Firefox stable (60 at time of writing) is not available from the Debian repositories- I downloaded the stable version and extracted it in my /Downloads folder. I'm running it from there at the moment, although desktop integration is possible. Details on the Debian Wiki.

Debian Stretch itself has Fireox ESR 52. Mozilla has released Firefox ESR 60, but I don't know when or if that will arrive in Debian Stretch- Firefox now requires Rust, and won't compile in Stretch because the version of Rust is not current, and Debian Stable does not include programs that wil not compile inside Debian Stable.

That at least is the situation as I understand it. Whether Firefox ESR 52 will receive security updates for the life of Stretch, or ESR 60 somehow be backported I do not know.

Extend laptop battery life in Linux?

I came across a thread at the Debian User Forums a while ago on this subject. One post there suggested installing TLP.

The Mint Guide suggests you need to run 
# tlp start
once to start it.

I don't use my laptop very much at the moment so I haven't been able to test it. At some point I will try to get round to doing a test and post an update, but if you find laptop battery life is poor compared to Windows, maybe try this.

Cancel print job in Gnome (Debian Stretch)

After over a year of using Debian Stretch, I finally found an issue to write about: it doesn't seem to be possible cancel a print job from the Printers dialogue in Gnome.

Possibly it's this bug, which seems to have been fixed just a few weeks previously to this post, so will still be affecting Stretch.

A solution I found here is to run the CUPS interface and delete the job from there:
http://localhost:631/jobs/
Cheers Zwets for that!
