GLV does reduce performance loss of aged RAM

"While most issues with computers slowing down are well known, and
pretty much a solved problem. There is one that is only slowly becoming
noticeable as systems get progressively faster.

This is the problem of memory slowing down as it ages."

To work around this issue, it's possible to use GLV.

Migrating from QupZilla to Falkon - Was: Is Ubuntu Linux protected against the Meltdown and Spectre security flaws?

The bellow workaround seems to do the job. I didn't notice another

Begin forwarded message:


for testing purpose I simply removed the Falkon's config and copied
QupZilla's config.

rm -Ir .config/falkon/
cp -ai .config/qupzilla/ .config/falkon

By the Preferences dialog I edited qupzilla:speeddial to
falkon:speeddial , could there be additional issues that might need to
get fixed?


Bootloader - Was: Re: How to clean up full /boot safely?

When I migrated from GRUB to syslinux I was euphoric, if you google long
enough, you might find claims from me similar to, "I got rid of the
GRUB crap, syslinux is the Holy Grail". Nowadays, I'm more careful
regarding such claims. Sometimes I'm thinking about migrating back to
GRUB. I've got good reasons to still stay with syslinux, but IMHO GRUB
is a good default bootloader, for user-friendly major distros. The way
too small /boot partition of Ubuntu default installs has less to do with
the bootloader. IMO sperating partitions from the root directory is for
hysterical raisins.

Meltdown – Spectre - Was: kernel 4.4.0-108 / 16.04 LTS does not boot anymore

Since a DAW not necessarily is connected to the Internet at all, but
requires best performance, disabling might be better, than using the
KPTI patch set and suffering from loss of performance.

do you have any hints on what to consider, when writing a script for an
LCD monitor and a CRT monitor using an Intel graphics?

I already have done some research on my own [1], but actually I booted
with an xorg.conf, IOW it's not removed yet.

LCD monitor


mainly for Ardour usage, but also for office work, browser etc. I want
to get rid of my CRT monitor. I wonder how much difference is between a
300,- € and a 150,- € LCD monitor.

Regarding a test the 8. best monitor is an Eizo FlexScan EV2450
the 48. best monitor is a LG 24MB56HQ-B

Both are 24" monitors. I can't say anything about the quality of this
test but at least the test was updated, a few minutes ago the rankings
were 7.

Anybody running Ubuntu in VBox and/or another VM?

tar - How to exclude a directory?


this is from a backup script:

It should exclude the
directory /media/winos7/winOS_2/ardour_ragrug-2017-mar-21-DONT_DEL_AT_IO_ERROR/cubasis

In the style of "dwarf planet".
If an editor is considered a moon, an IDE could be a planet.
So something more than an editor, but less than a bloated IDE, might be
a dwarf IDE. Analogies aren't perfect.

Cheap mobo that doesn't cause issues with Ubuntu.


I need a new mobo and PSU, this unfortunately means a new CPU and new
RAM, too. Does somebody use on of the following components or could
recommend for or against one of those components [1]?

Could somebody recommend something else?

The mobo must provide at least one PS/2 socket and one PCI slot, not
only PCIe.

Current_Pending_Sector value on a brand new HDD


I've got a new SSD and two new HDDs.

The SSD is ok, but I wonder if the two HDDs are ok, too.

The TOSHIBA DT01ACA100 is inside the PC case and at the beginning
it caused click noise and input/output errors only repeated shutdowns
made it accessible. The WD3200AAJS is used with a FANTEC DB-ALU2E
by USB. It automatically goes to sleep. If it goes to sleep as
e.g. /dev/sdd, it could wake up as /dev/sde and sometimes it could
completely hide. However, since my last reboot it goes to sleep
as /dev/sdb and wakes up as /dev/sdb.

What has fsck -vcck done, to repair a partition?


I already ordered a SSD to replace a fishy HDD. For the moment I run
fsck, since one file caused input/output errors when tar, cp or string
tried to read the file. When it failed, the HDD made click noises.
The file seemingly is repaired, but I don't understand what fsck has
done to repair it [1].



I plan to replace two drives [1]. I'll start with the small drive,
since it seems to reach end of life. Today everything was ok, but
sometimes it seemingly is the cause for serious issues.

The larger drive seems not to cause issues, but it's also very old.
I'll replace the large drive by a 1 or 2 TB HDD, but not right now.

Commentary on file managers vs terminal/command line


even the few very good file managers could get broken after an upgrade.
Even an upgrade of a theme could render a file manager useless, let
alone that there could be serious bugs in the code of a file manager. A
user could lose files! Thunar is know for serious bugs and upstream
doesn't fix those serious bugs. Reading the Nautilus thread users claim
slow performance. I noticed this for newer releases of Rodent, too.
Note, Rodent does use regular shell commands, a user could edit those
commands, so some GUI crap adds the slowness.

read a single pushed key by a dash script


since some script experts are online at the moment, does anybody know a
more neat solution, than using bash's read in a dash script?

bash -c "read -n1 answer"

Btw. I'm using this for a script that could run as dash and bash
script, it's just that dash is faster. It doesn't matter for this
script at the moment, but you never know, speed could become an issue.


'sudo id -G <username>' vs 'id -G' issue


I need to run a script with root privileges. One thing this script
could do, is adding a user to a new group. Sometimes the script doesn't
know, if this is already active for the user. IOW the user is already
member of the group, but didn't log out and in again, resp. didn't
restart the display manager.

LightScribe Ubuntu >= 16.04 (64bit)


yesterday I needed LightScribe, but the LightScribe software doesn't
recognise the drive. I installed it on Ubuntu Xenial 16.04 (64bit), as
well as Arch Linux (64bit) and it failed on both installs. Around
midnight I have given up troubleshooting and used LightScribe of an old
Ubuntu Quantal 12.10 (kernel 3.6.5-rt14 64bit) install, its end of life
was 2½ years ago.

Has somebody successfully used LightsScribe with Ubuntu >= 16.04?


multi-user guidelines for shared folders


is there a guidelines how to name directories and files in shared folders,
e.g. in /tmp on multi-user systems? And apart from the names, how
should permissions be handled?

User? PID?

Fw: Final release - was: Testers wanted


those who want to test different Ubuntu desktop flavours [1] might want
to use a script to automatically download all files and do the complete
check as described by <a href="" title=""></a> .

Save the script [attachment].

Make it executable by running

chmod a+x


The default flavour is ubuntu-mate.
The default release is 16.10.

Other desktop flavours available for at least 16.10, but perhaps for
other releases, too

Manual for apt


where do I find an English and a German manual for apt?

Packages installed by either apt "full-upgrade" or "install", e.g.

# apt -o APT::Color="0" full-upgrade
# apt install alpine-pico

are not stored in /var/cache/apt/archives/.
As wanted apt-get "dist-upgrade" and "install" stores the packages in
the cache.

Some apt-get options seem to be available for apt, too, e.g.

# apt-get --fix-broken install

Building dependency tree
Reading state information... Done

# apt --fix-broken install

Transitional kernel packages
