LM  .. long mode, is it ?

 

Then it could equally describe the drinking session I'm having during this wonderful, hot, cold, sunny, overcast, calm, blustery, 'droughts and flooding rains' (Dorothea Mackellar) kinda Australia Day.

Aussie Aussie Aussie oi oi oi

Yes, and damn it .. I'm using the terminal more and more .. you guys ..

That is where the fun really begins!

But only if you want ...

Quick question - does anyone know whether LMC has a screen brightness adjuster - something like 'display - brightness' in W7 ?

 

Have looked but can't find. And there are no buttons for it on my keyboard (that I know of ?).

Hi Mate I haven't used this but you could go to:

 

Menu - System - Control Centre/Center - Look and Feel - CompizConfig Settings Manager, click OK for the warning, then

 

Accessibility - Opacity, Brightness and Saturation

 

... and have a play?

I have a Windows system that needs a good cleaning......more than CCleaner or Disk Cleanup ran as Administrator can provide, will give BleachBit a shot on that one. 

 

Should anything bad happen, no worries, just imaged the SSD hours ago.

 

Though on Linux, I do use it as stared above, only for those purposes, does a fantastic job of cleaning behind lots of browsing activity. On a HDD, using the overwrite option, still took less than 3-4 minutes to run & that was several hundred MiB's of data erased. Close to 1GiB. Unlike CCleaner, it doesn't give the 3, 7 & 35x overwrite options, believe it was a single one, plenty enough for most users. 

 

One doesn't want to use the overwrite function on a SSD, the result will be a fast worn out unit & the OEM won't cover this type of damage, no matter how long the warranty may be.

Hi cat - highlighted ..

I would be very interested to know of your results.

 

 

BleachBit found a little over 450MiB of files on a well aged (unusual for me) Windows 7 install that is on it's 4th-5th clone, have lost count, other than it gets knocked to the oldest (or worst) SSD I posses, feel that it's found a permanent home on a Samsung 250GiB 840 EVO. Cleaned successfully!

 

While on Linux, I don't dare check all of the boxes, one means to overwrite the contents, which should never be performed on a SSD, and compared to the four pane dungeon like looking OS, it would take Linux 10+ years to create as many Temp files as the other does during the initial install. Which happens to be over 1GiB on the world's most popular OS from updating alone & can be as high as 2GiB. Have never in my life seen that amount of System Temp files on a Linux install & likely never will. As Wiz noted, I had a very bad experience with BleachBit (as did Nick), as well as the more dreaded 'Computer Janitor', that while I'll clean the browsers & Flash cookies with the former, will never install the latter on any Linux install again. Some of these offerings in the Software Manager gets updated, while others doesn't, or are outright dangerous to use. Opera 12.16, which any Ubuntu (& derivatives) users can pull up, is a fine example of this in motion. Was released probably 3-4 years back at a minimum. 

 

That's another of the rarely unspoken beauties of Linux, the OS does a fantastic job of tidying up behind itself. Usually, my Internet cache is much larger than any Temp files would be, though we have more control over this with Firefox than Chrome. Firefox an option to override cache management (default is 350MiB), I've reduced this to 50MiB for now, if ever Firefox becomes my default browser again, will raise the limit so that I won't lose files while in session. 

 

As far as the 400MiB or so of Temp System files on my 40GiB root partition with only 8.45GiB used, when these grows to consume a meaningful amount (or the contents of the entire root partition exceeds 50% of the space on SSD), will simply reinstall the OS & make adjustments. While the effect cleaning System Temp files may not be seen at the moment, there's a chance that one day, an app that you need may be broken over the loss of those files, and in the worst case, will show negative effects immediately. When I install a OS (regardless of brand or version), will plan the install accordingly, so that space isn't an issue, this is what led to the purchase of a new 1TiB HDD last year, had a 500GiB one in place, wasn't enough for the needs of all 4 OS's on the PC. Just my Mint /home install needs half of that space for future growth, though being a HDD, can go above the 50% rule & still leave 10% free (unformatted) at the end for overprovisioning. 

 

Samsung outright recommends this amount for overprovisioning, or more if one can spare the space, while others recommends 7% minimum. It helps the controllers does their job in keeping the drive clean & having best performance. So does having partitions less than 50% filled, though the 400+MiB of Temp files are no threat to that, and 60% is the most one should go over. 75% is deemed the 'critical' level for most all brands & continual running a SSD (or partitions) that full will result in permanent reduction of performance/lifespan. Users who are filling a SSD to these levels are more likely to reach the TBW allowed, prior to the warranty ending, just like an auto. If the TBW (Total Bytes Written) is reached before the 3/5/10 year warranty, that's the end of warranty. While an SSD is not a delicate item, if one has lots of files to store, it's best to purchase an extra large capacity model (1-2TiB), or store otherwise less accessed data on a HDD. Most old school notebooks has an optical drive, which for around $10-15, can be replaced with a HDD caddy to place their OEM supplied HDD in, and a $5 cable will allow one to use their optical drive as a USB one. Or to have a pair of SSD's, and just get an all aluminum USB 2.0 caddy for less than $6 on eBay for storage/backup purposes (first link below). I have three of this model for my USB 2.0 only computers, could use another, as well as another USB 3.0 model (2nd link) that reaches backup speeds of nearly 1.5Gb/sec (read & write combined). Why pay over $20 for such an item, when an entire 1TiB backup drive can be found on promo for $40-45 (if Newegg subscriber, there may be others).

So one must consider the type of drive being used when managing space.

Since this topic has turned into something not even remotely resembling the intended subject matter, it will now be closed. If someone wishes to create a general subject matter topic thread. Then be my guest. I can tell you, anyone clicking on a 31 page 'My Linux Experience' topic would never give Linux a chance if they read this topic start to finish. This topic goes so far off the rails I don't even know where to begin.

With that thought in mind it's time to close this topic as a reminder of how not to maintain topic continuity.
