Exactly. I can rarely remember the run command hotkey. If I did, I'd open
Konsole and try doing things from that, or run command.
Try Alt+Shift+F12, this toggles the desktop effects. I use it on a PC (not
alternatively, programmatically:
kwin_compositing_active=$(qdbus org.kde.kwin /KWin
org.kde.KWin.compositingActive)
[ ${kwin_compositing_active} = true ] qdbus org.kde.kwin
org.kde.KWin.toggleCompositing
You can also edit ~/.kde/share/config/kwinrc, and set Enabled=false in the
[Compositing] section.
Alex,
I prefer to state modifications to config files in terms of k{read,write}config
statements, as these should work regardless of the distro (i think). This
should make it easier for end-users to get the desired effect w/o having to
hunt around or try to figure out why a section/key/file don't exist.
Just Cut/Paste and voila' (crossing fingers...)
see below...
That would not be a global fix. That file doesn't even exist on a new install
until after KDE gets started, and then only for each individual's first login.
On Natty, I looked and found only one kwinrc, hiding in a directory called
/usr/share/kubuntu-netbook-default-settings/share/config, which makes no
sense to me, since this is a desktop install, not a netbook. Looking on the
mirrors in pool/main/k/ I see a kubuntu-netbook-default-settings/, but
nothing that looks appropriate for a desktop installation.
On 11.4, I couldn't find a kwinrc in any of /etc, /opt, /var or /usr.
Anyway, would the kwinrc file in Natty's /usr rats nest be appropriate for
global changes? It has no [Compositing] section.
Felix,
This will work to disable compositing for the user that runs it (after logout
and log-back-in, or if they've never logged in yet:
kwriteconfig --file kwinrc --group Compositing --key Enabled false
This should work to create a SITE-specific (or machine specific)
Override (that should not be touched by system updates). This will/should
create files, group sections, and keys as appropriate
if they don't already exist.
kde_etc_config=$(kde4-config --path config | cut -f2 -d:)
kwriteconfig --file ${kde_etc_config}/kwinrc --group Compositing --key Enabled
false
At least this all Works for Me(tm) ;)

I use it on a PC (not Another hotkey combination I'll probably forget as fast as I discovered it, or at least not remember when I need to. FWIW, for such things I tend to (try to) remember mostly that something is /possible/, along with enough about it to look it up again or ask about it later, should the need arise, as opposed to (ineffectively) trying to remember specific details. The more general approach seems to work quite well, for me, as I'm able to retain general data about far more tricks and workarounds than I might otherwise remember, generally enough to successfully look it up later, if it proves to be needed. This stands me in good stead not only personally but in all the various lists I follow, where I can thus more often be of help to someone experiencing an issue I'd never come across on my own. In this case, it sounds like you tend to have access to more than a single computer. As such, all you need to remember is that there is such a keyboard shortcut, and you can look up the details on a working system, should you need it. But chances are, after doing that a couple of times, you'll remember it anyway, because then you'll have enough additional actual experience with it to create an associated memory that's much harder to forget the details about, than some arbitrary hotkey combo with no actual experience to back it up. What I'd therefore try to remember in this case, is that such a hotkey- combo exists, and where one finds it on a working system -- in the same place one might find other similar hotkey-combos, in kcontrol (systemsettings that aren't system-settings -- actually the problem you have here but see below, but rather, user-specific kde settings, so the kde3 term kcontrol remains far more accurate and is thus the term I use). In kcontrol, the key is to remember to look for shortcuts. In this case, it's under common appearance and behavior, shortcuts and gestures. Once there, one has to choose between three different modules, custom, standard, or global, and getting the right one the first time might be difficult. But there's only three, so if one isn't it, the next is easy enough to switch to. In this case, we want global keyboard shortcuts. Then you must figure out which kde component that shortcut controls. Looking at the available choices, kwin looks likely, and indeed, that's where the setting is found. Then you have to find a description that matches your memory of the function you're trying to find the hotkey for. The keywords suspend and compositing, whichever one you happen to remember easiest, is next. Sure enough, suspend compositing is a listed action. Clicking it lets you see what the default shortcut is, for that. So if all you remember is that it's compositing that you're trying to control and that there's a hotkey for it, plus have the general knowledge that such settings are configured in kcontrol/systemsettings (that aren't systemsettings...) you should be able to look up the specific hotkey on a working system, looking for shortcuts in kcontrol, and using general logic to find the specific module and setting after that. Meanwhile, it won't help here but for actually use and FWIW, I've reassigned most of the various kwin shortcuts I actually use to winkey- modifier shortcuts. In kde, the windows key is normally listed as meta (or occasionally as super), but remembering win-X, where X is usually the first letter of what I'm trying to do, and the winkey is associated with kwin, that is, windows functions, is a whole lot easier than the arbitrary alt-shift-control-fN keys that kde defaults to. So win-s toggles suspend compositing here, win-g triggers the desktop-grid effect, win-c triggers the cube effect, win-ctrl-s (win-s being already taken) toggles the snow effect, etc. (win-end closes a window, win-pgup maximizes, win-pgdn minimizes, win-home rolls it up into the titlebar, win-insert

I'll keep that in mind, but I just stumbled onto something that looks
(possibly) easier, and even more global (since it's in /etc/, where global
config files belong) on the ATI mailing list.
http://lists.x.org/archives/xorg-driver-ati/2011-July/020647.html
quote
I put a file:
/etc/X11/xorg.conf.d/composite.conf with the following:
Section Extensions
Option Composite Disable
EndSection
/quote
I almost always need tweaks in /etc/X11/xorg.conf or /etc/X11/xorg.conf.d/
anyway, so this would be a minor change to what I'm already doing, if it
works regardless of distro. I'm usually multibooting, and all distros added
after the first on a system I typically pre-config with things like HOSTNAME,
exports, profile.local, resolv.conf and more.
