<br>
That's an interesting question. Short answer, I don't know.<br>
<br>
Back in still severely buggy 4.2/4.3 period, when I switched from kde3, I<br>
distinctly remember a number of individual desktop launcher icons, one<br>
each for the few I had on my kde3 desktop.<br>
<br>
However, being the heavy customizer I am, and with the various bugs<br>
triggering crashes and restarts, those didn't stay around long, and I<br>
wasn't yet familiar enough with the system to know which plasmoid they<br>
actually were, so I really don't know if they were simply quicklaunchers<br>
configured with just a single icon each, or if they were export-only<br>
plasmoids that aren't available in the plasmoid explorer, or something<br>
else.<br>
<br>
Plus of course not knowing what they actually were, for all I know they<br>
were some plasmoid available in early kde4, that was phased out somewhere<br>
along the line.<br>
<br>
I've sort of wondered what they were a few times, but icon-based<br>
launching isn't really my thing anyway, so it's not like I'd be likely to<br>
use them. But I'd still like to know for sure what they were, just on<br>
principle. (FWIW I prefer hotkey based launching, and ended up scripting<br>
my own solution after kde4 broke the khotkey multikey support I had used<br>
in kde3.)<br>

Eh, my theory is that sometimes asking that so-called "stupid" question<br>
is often part of finding the answer. Delay the post hoping to come up<br>
with the answer yourself, and it doesn't come. 10 minutes after posting,<br>
tho, you have it!<br>
<br>
That's been my experience anyway. So these days, if it looks like that<br>
sort of question, I try to post it as soon as possible, figuring the<br>
sooner I post, the sooner I'll have the answer, regardless of whether<br>
it's because I figure it out 10 minutes after posting, or because someone<br>
else points me to it.<br>

<br>
likely slow "blur" desktop effect, I see that on my older intel945-based<br>
laptop too. disable the blur effect, and it's much faster.<br>

<br>
Hi fellow kde gentooer! =:^)<br>
<br>
I haven't updated it in awhile (it's not my primary system), but I run kde<br>
on my original Acer Aspire One netbook (AOA-150L model, Atom n270,<br>
upgraded memory maxed out to 1.5 gig, pre-poulsbo Intel graphics tho I<br>
don't recall what exactly, but I specifically ordered the model with the<br>
"spinning rust" hard drive, 120 gig, as I was looking for 100 gig plus).<br>
<br>
KDE runs fine on that, tho it /has/ been awhile since I updated; I think<br>
it's still running late 4.6 so it has been over a year.<br>
<br>
Rex has the right idea, tho. Try experimenting with the effects. I<br>
don't recall having serious issues on that system here, but some Intel<br>
graphics hardware is known to have issues with blur, etc. Apparently the<br>
drivers claim the hardware handles certain effects, but really emulates<br>
them in software. That's good enough for a lot of games, which often<br>
require a feature but then don't really use it, but it makes the desktop<br>
SLOOOWWW when effects using those features are active. Fortunately,<br>
individual effects can be toggled on or off. =:^)<br>
<br>
That option's located on the middle tab of desktop effects, in kde<br>
settings, workspace appearance and behavior, BTW.<br>
<br>
Meanwhile, you don't mention your memory capacity. If it's a similar<br>
netbook, many of them shipped with half a gig or so of RAM. I upgraded<br>
mine to 1.5 gig (the half-gig soldered on, and a 1 gig stick upgrade, the<br>
max the bios was said to recognize) really early on, before replacing its<br>
default Linux with gentoo, so don't really know how kde would work on it<br>
with the original half-gig, but that /might/ be an issue. Going into<br>
swap on those early SSDs was SLOW, as writing to them was slow. Plus SSDs<br>
are limited write-cycle, so I bought the netbook with the 120 gig<br>
conventional hard drive option and the intent to upgrade the RAM, which I<br>
think I did within days of purchase.<br>
<br>
You can also check the konqueror performance option that keeps a copy<br>
loaded at all times. On a low-memory system that'll be a tradeoff,<br>
taking longer to load kde if it loads konqueror with it, but in theory<br>
it'll start konqueror faster since it's already loaded. OTOH, if the<br>
system's really low on memory, it'll swap out that konqueror instance,<br>
and will thus be loading it back in from SSD anyway. Between that and<br>
the fact that it'll be taking memory even when you aren't "running" it,<br>
if you're swapping anyway, turning that option off even if it means<br>
longer konqueror load times may help with other apps.<br>
<br>
You'd also want to consider the minimize memory usage option.<br>
<br>
Both of those options are in konqueror settings, performance.<br>
<br>
<br>
Meanwhile, since you're on gentoo and can, especially on a small system<br>
like a netbook, consider USE=-semantic-desktop if at all possible. It<br>
make a BIG difference on my main system, even tho it's not as resource<br>
constrained as the netbook. That DOES mean you'll need to find<br>
alternatives for any kdepim apps you run, but it should be faster. Here,<br>
it was *MUCH* faster -- I was surprised at HOW much faster! FWIW, I run<br>
claws-mail for both mail (replacing kmail) and feeds (replacing akregator)<br>
now, tho the conversion from kmail was a bit tough. But it's worth it!<br>

massive login latencies (1-2 min) are often the cause of DNS or<br>
network i/f issues... Make sure your resolv.conf is happy, and that<br>
your network interfaces are as well (make sure that your loopback<br>
i/f is active)<br>
<br>
Check in the .xsession-errors file for any obvious problems.<br>
<br>
quickly...<br>
<br>
host <a href="http://www.google.com" target="_blank">www.google.com</a><br>
host $(hostname)<br>
ping localhost<br>
ping 127.0.0.1<br>
ping $(hostname)<br>
netstat -in<br>
<br>
if any of those are taking a long time, you probably have a network issue)<br>
<br>
in xterm or konsole, also check :<br>
echo $DISPLAY<br>
should be :0.0 (don't ever globally directly set DISPLAY. Change it<br>
only for a specific instance manually and interactively as needed)<br>
<br>
I'm not sure about issues you may be facing booting from flash-disk,<br>
but if you're *swapping* to flash disk, that may ultimately create a<br>
VERY slow flash disk.<br>

Well, the answer is most probably no. I just check on my Slackware<br>
13.1 box with KDE 4.4.3 and an openSUSE 11.2 LiveCD with KDE 4.3.1.<br>
<br>
Neither has such a plasmoid, and actually on the Slackware desktop,<br>
there was a single-icon quicklauncher which I had put there (damned,<br>
are my glorious Slacky times really gone ;-) )<br>
<br>
So, scratch this. /-)<br>

Yep, I know what you mean. :-D<br>
Still, I tend feel a little embarrassed when asking a question which<br>
turns out to be a time waste or a simple oversight. But it's like a<br>

I would be willing to bet it is the flash disk at fault. I have built<br>
several systems using various kinds of flash devices for filesystems. I<br>
have always blamed it on KDE's use of tons of small files and poor small<br>
file performance of flash devices. Try moving all your temp directories<br>
to ram and see if that makes a difference.<br>
<br>
Try mounting /tmp and /var/tmp to a ramdisk and see if that makes a<br>
difference.<br>
<br>
My /etc/fstab looks like this:<br>
<br>
tmpfs /tmp tmpfs mode=0777,size=24M,nosuid 0 0<br>
tmpfs /var/tmp tmpfs mode=0777,size=24M,nosuid 0 0<br>
<br>
<br>
Try doing the same and let us know how it works.<br>
