I wonder if that works in Linux since the wikipedia article doesn't say,
only that it works in unspecified Windows and not in MacOS 10.15
Catalina. Not that I have any displays with the requisite DP outputs so
it's snakey cabley city on my desk.

DVI doesn't carry audio. DP does.

An M92p has a DisplayPort (DP++) connector and a VGA connector. An 
old VGA monitor can be connected directly.

Any advice about choosing an adapter to connect DP++ to the DVI 
connector on a 2nd monitor?

Any advantage in finding a way to connect two monitors to the one DP++?

AIUI early versions of Xfce4 used GTK 2 and versions beginning with
4.13 use GTK 3. So yes Xfce4 on bullseye uses GTK 3.

There's some information about installing different themes at
https://wiki.xfce.org/howto/install_new_themes

It's perhaps worth noting that quite a few GTK themes seem to have
obscure bugs that affect the appearance of some applications but not
others, so your experience may be better or worse than other people's
depending on which applications you use. Mainstream choices generally
seem to be safer.

False. Not even half the male population in ancient Athens were citizens.
Even the "police" (from the Greek "polis", city) were slaves owned by
Athens itself, not an individual. Of course no female could be a citizen.

That information was revealed in the early 1970s by the Watergate hearings

against the FBI and its counter intelligence program. It's nothing new, but
plenty of Americans forgot about that or never knew. And lots of Americans
like those unconstitutional government programs too.

XFCE4 uses GTK3. There are still some applications that use GTK2. You 
can install new themes and select them under Applications / Settings / 
Appearance / Style. You can also install alternate icon sets (selected 
under Appearance / Icons). Some themes support both GTK 3 and GTK 2 and

Both. Some XFCE4 programs that comes with Bullseye use GTK3, others
GTK2. And the GTK people are working on GTK4. If there's a unified way
to change themes or modify them, I've not heard of it.

Interesting, doing a Google search finds that SD cards do support
this... https://superuser.com/a/1554860

Though that was with an actual MMC device though, don't know about the
interfaces which now all seem to be implemented at the end of USB. In
fact the forum reply above says:

   USB to SD card adapters ("SD card readers") could support this
   command by advertising the TRIM or UNMAP commands via the USB
   storage interface, and translating these to the MMC_ERASE command,
   but I've yet to find a USB adapter which does this.

If you are very lucky, yes, but most of the time: no. And it is
kinda risky.

Imagine your install from experimental/unstable/testing wants a
newer version of some basic library (think libc). You install
that and break all other applications using it (NB: the installer
will go out of its way to prevent you doing that). With a huge
package like LO, I'd say the probability of something like
that happening is rather high.

> if so, how?

That's what "backports" are for. Either you wait for some kind
soul making a backport to your distro series, or you try yourself:
download the package of your wishes, install its build dependencies
and build. Here[1]'s a bunch of more detailed instructions, and
do ask here if you get stuck.

You probably can't. I've not heard of removable cards supporting the

I found a issue_discards setting in lvm.conf. Set that, then created a

There's definitely something implemented on sd cards: fstrim works on an

Hi,

You probably need to import the key from their repository and add it to your 
local keyring. That will mean that the error will go away.

In most cases, repositories will supply the instructions to do that.

You said 'unless the card is brand new'

Only in the case where the SD card has at some point been completely
full, and you maintain cases where that isn't true is 'pathological'.

Guess my storage uses are pathological then, because apart from the
extreme example of that restricted 4GB partition I use for a root
filesystem, my other 'normal' usage doesn't fill removable flash
storage either. E.g I copy images and videos from my digital cameras to
my PC then delete them from the cameras, and the backup storage on my
keyring I carry around isn't full. (Backup storage performance falls
badly as it fills, presumably due to lack off readily available erased
blocks, so that tells you to go buy a bigger flash stick :-)

Customize XFCE4

[Klaus Jantzen]

Hello,

I, finally, installed Bullseye with XFCE4 as desktop environment.

On the desktop, how do I change the color of the text under the icons 
(which is now white) to black?


The information about themes I found is somewhat confusing as there are 
references to GTK-2.0 and to GTK-3-0.


Which GTK is actually used?

Thanks for any hints.

Good for you. But constructors will not design cards for this niche use
case. Cards that gets almost filled are common, constructors will have
optimized their process to handle them.

For flash media, most of the time, "pathologically underused" is in my
view "recommended state". My back-up USB stick is less than 50%. Once
it reaches significantly more than that, I look around for one with four
times that capacity.

(And yes, it's LUKS encrypted, but I don't bother to overwrite the
whole thing with random data: a small information leak I live with).

Has served me well for many years.

Indeed. And as I said already, unless the card is pathologically
underused, “what blocks of flash have been written to” eventually
becomes “all of them”.

So you have two options:

- Either when a card has been written in (almost) full once it stops
  being able to do wear-levelling and quickly dies.

- Or the suggestion that this is how wear-leveling works was wrong and
  based on insufficient reasoning about the mechanisms involved.

> So, if like me, you have a 64GB card, with just a 4GB partition

Pathologically underused. A more typical use of a card would be “damn,
my camera/phone/recorder tells me the card is full, I need to copy a few
things to the cloud”.

The card could know what blocks of flash have been written to, it's the
thing that has done the writing. Very simplistically, if the OS writes
to sector N, card has to allocate a block of flash to contain the data
for that sector. If OS writes to sector N again, card has to get an
erased block of flash to write new sector data to, then it can erase
the old block of flash which it now knows is unused. (Note blocks are
much bigger than sectors, and the data structures and algorithms for
keeping track of what's where will be proprietary 'magic'.)

So, if like me, you have a 64GB card, with just a 4GB partition
containing a filesystem, then the OS will never have written to sectors
outside that partition and the controller on the card would never have
had to allocated flash for them. Therefore it can know about 60GB of
unused flash, plus whatever extra reserve the card was manufactured
with.

What SD cards actually do in reality though, I don't know.
