The Microsoft ecosystem

I've just been working on an old Windows Vista laptop which I was asked if I could fix. Apparently it had had problems with a virus and the owner couldn't get on to her online email.

Trying to boot the laptop only resulted in endless failed attempts by Windows to repair itself- the system was obviously broken. I managed to find a Vista repair disc, which fixed the boot problems. Microsoft of course doesn't make these discs available, and tries to take down any copies that appear on the web. You are apparently supposed to use the system recovery partition- and then spend many hours downloading all the updates and service packs that have accrued over the last decade.

Booting into Windows was just the beginning of my problems. The laptop was locked up with constant I/O on the hard drive and processes taking up most of the available memory and CPU.

I booted into Safe Mode and used the AVG removal tool to remove AVG, which was loading into memory but not working, and installed some updates which a web search suggested might be the reason svchost.exe was locking up the system after a normal boot- automatic update trying and failing to install updates.

After that, a fairly normal boot. Multiple malware scans found only one Adware file and a few PUPs. However, I noticed that the C: partition was almost full- over 30GB- and showing red. Vista seems to store user files in C:, so I imagined I'd find a huge collection of photos or MP3s taking up the space- but no, it seemed to be Windows cruft: packages of updates left after the installation of Service Packs.

The D: partition was almost empty, and a similar size to C:, so I thought I'd resize C: to give the system more room.

Now Windows Vista will let you shrink D:, but it won't expand C:, because it's a boot partition.

I came across a post on answers.microsoft.com which kindly suggest some free programs which would shrink the D: partition and extend the C: partition. I used the first one, and here's where the real trouble began.

I noticed an annoying pop-over add for System Mechanic which told me it was a Microsoft Trusted partner, and if I ran it's scan, I could save myself from endless system crashes. (Microsoft partners tell you that Windows is so rubbish it will keep on crashing unless you emply a third party to fix it?)

Well I ignored that and used the partition program from EaseUS to resize the partitions, and it did work really well. OK, I was only going to use it once, so thank you for making it available for free. Software developers have to make money, so seeing an advert seemed a reasonable price to pay for using a good bit of software.

You might think that if Windows is going to fill its partition with cruft, they might give you the tool to fix it, but they've been in trouble before for trying to monopolise the market, so maybe they decided to throw a few crumbs down the food chain.

The problem is that where there are crumbs, there are bottom feeders lurking.

When I tried to update a program on the computer, I found that the web browsers were showing pop-up advertisements and redirecting me to other sites.

An example of the most stupid adware that makes browsing the internet almost impossible: if you can get to the site you want to visit without being redirected, it is almost obscured by advertisements, and links never seem to take you to where you want to go.

A scan by MalwareBytes revealed Conduit, OpenCandy and Roll Around were the culprits. Getting rid of everything found seemed to fix Internet Explorer, but Chrome was still showing Roll Around adds in web searches and redirecting to unwanted sites.

AdwCleaner and ESET Online Scan found and removed more traces, but Chrome was still infected: evidently some sort of hidden extension. In the end, I had to uninstall Chrome and reinstall it to fix the problem.

EaseUS should be ashamed of themselves. They have a good product, which people try to use to fix a problem, but their way of getting a financial reward for their work leaves the users of their product virtually unable to use the internet, and very probably, like me, angry and frustrated, although unlike me, possibly not having the skills to remove the despicable adware they have installed.

There are ways to get paid for a supplying a product that don't involve abusing your users- asking for a donation or a purchase of a full product, or showing ads that don't inconvenience the user.

The sort of model that MalwareBytes and AdwCleaner and ESET use- at least the existence of bottom feeders provides food for these more salubrious eaters.

But that reminds me of what the guy who made available the Vista disc I used in the first step of fixing this laptop wrote to accompany it:
I strongly advise you to at least test the best operating system available TODAY, namely Linux MINT Xfce (try Linux Mint 17 Xfce, codename 'Qianna', for newer PC's with Windows 7/8 or Linux Mint 13 Xfce, codename 'Maya', for older PC's with XP or Vista): you will be pleasantly surprised how much better Mint is compared to Windows and it is FREE, FOREVER FREE [and you will be forever free not only from the expenses associated with Windows but also from all the angst, all the hassles, all the troubles, all the virii and all the spyware associated with Windows!].
I'm not a Mint user myself, but having just installed it on an old computer,I'm inclined to agree with him: if you have an old Vista computer and could do without all the hassle I have just described, give Mint a go!

The ecosystem is a lot nicer.

RTFRN

I've just installed Linux Mint XFCE on an old AcerPower M-8 for somebody who wanted to try Mint.

First attempts resulted in screen lock ups.

I guess I should have Read The Flippin'  Release Notes.
If you are unable to boot Linux Mint with an NVIDIA card, or if you are experiencing constant freezes and system lock ups, please append "nomodeset" to your boot arguments. At the boot menu of the live DVD/USB, press Tab to edit the boot arguments and add "nomodeset" at the end of the line.
Release Notes for Linux Mint 17 Cinnamon

Actually, you have to add "space" "nomodeset" to the end of the line:
-- nomodeset
I missed out the space and thought it had worked because the install seemed to work. But, after a couple of hours, right near the end, the screen froze again.

Having corrected that piece of stupidity, the install completed. Very. Slowly.

Yes, the install process takes a long time on this computer. Pick up a copy of War and Peace to read in the meantime.

I have to say, Mint looks very good- better than a default XFCE install on Debian.

But the computer runs out of memory very quickly and grinds to a halt with more than one application running, or a background process like update open. (Default update period was set to 30 minutes- which meant the computer ground to a halt every 30 minutes.)

A bit surprising as I have an old laptop with a similar amount of memory (512MB) and a slower processor that runs several applications in Debian XFCE without struggling.

Mint (based on Ubuntu) seems to be heavier than Debian. The laptop was running Ubuntu until 2009, when it ground to a halt after an upgrade. It ran Debian OK, even with 256MB memory which it had at the time.

I have just ordered 512MB of (hopefully) compatible used memory from Ebay for the ridiculous price of £1.69, so with any luck, that will make the computer more usable.

If you are installing mint on an old computer, check out Ebay for a memory upgrade if you don't have the 1GB required for a "comfortable" experience as mentioned in the system requirements.

Pick up a (long) good book to read while it's installing, and enjoy a very good looking and easy-to-use Linux distribution at the end.



Systemd overrides laptop lid close options in Gnome

If you are using Gnome on a laptop in Debian Jessie (or possibly any other Linux distro using Systemd), you may find that the When laptop lid is closed menu in Gnome Tweak has no effect: closing the laptop lid always suspends the laptop.

This is because the Systemd default overrides the Gnome option. To fix it, edit /etc/systemd/logind.conf and uncomment HandleLidSwitch and change from suspend to ignore, thus:
HandleLidSwitch=ignore

How to tranfer files between an Android tablet and Linux

I recently tried to connect an Android tablet to my Debian computer- and found the connection didn't work. Google told me the connection now uses MTP (older versions of Andoid, including my phone, used USB mass storage to connect) so I wondered if MTP was broken in Debian Jessie, but then I tried another tablet and it connected without a problem.

On the tablet that did connect, USB debugging was enabled, as well as MTP.

Now I certainly didn't enable USB debugging, because the menu option is hidden- you have to go to About tablet and tap Build number seven times which I didn't know about until just now, when I looked for the option and couldn't find it. (I discovered the information on greenbot.com.)

Nor did I enable MTP. (Go to Storage, tap the menu icon (three vertical square dots to the right), tap USB computer connection when it appears and tick Media device (MTP).

Enabling MTP on the tablet that wouldn't connect allowed it to connect. I also enabled USB debugging, which on this tablet wasn't hidden for some reason, although a subsequent test proved it wasn't necessary to connect.

However, on the second tablet, USB debugging is necessary.

Curious as both tablets run the same version of Android and are both from the same manufacture, although they are different models.

A useful reference from How-To Geek:

Update Flash fix security flaws! (The Déjà vu remix)

Flash seems to have been pwned again- as usual:
Flash updates are not automatically downloaded in Debian- a user has to do:

# update-flashplugin-nonfree --install
Restart the browser afterwards to load the updated Flash player.
KrebsonSecurity has the lowdown: here and here.
