Nerdfest's questions

When using KDE, I have the following occur after the desktop has been used heavily for several days: The compositor stops working properly for one or more applications.

An example of this would be with Chrome or KMail, which will stop responding properly to scrolling, stop updating their displays, etc. Proper functionality can be restored (at least temporarily) by turning compositing off, and then on again. (aLt-Shift-F12). This actually happened in KDE4 as well as the current KDE 5 release. It is generally most noticeable in Chrome, although that may be because it's heavily used.

The hardware in this case is an i7 laptop with an NVidia GeForce 670MX graphics card using the latest NVidia proprietary drivers.

This seems to be the opposite problem most people ask with KDE PM. I have a laptop running Ubuntu 12.10 and KDE 4.10. After the last couple of updates (I'm not sure which one), my screen stopped turning off after the power management timeout has been reached. This occurs with no screensaver, basic screensaver, or any of the others. It does seem to work the first time after a fresh boot.

Does anyone have any ideas about things I could check to get my screen to turn off?

Does anyone know of a way to get persistent Gnome 3 panel notifications in Gnome 3 in Oneiric? It's one of the few things holding me back from using Gnome 3 regularly.

I've actually found a way of moving the notifications from the (usually) hidden bottom bar to the top, but it does not move the Thunderbird icon. The icon also only tends to appear the first time mail is received. I'm very surprised this basic piece of functionality doesn't exist for Gnome Shell.

I've been wondering about improving the performance and battery life of my netbook by installing my root partition to an SD card. Will there be any performance benefits (or drawbacks)? Are there any special changes that should be done to make this work better.

This is a little different than the common Natty temperature applet question. I've given Unity a shot and have reverted back to Ubuntu Classic. The one thing that is still not working is the temperature panel indicator (on 2 different laptops). It reports 'No Thermal Monitor Support' and shows a big red 'X'. The temperature sensors are working as GKrellM can still report temperature properly. Does anyone have a solution?

The specific applet is the 'computertemp' applet. After Jorge asked for more details, I tried the other one, the 'sensors-applet', and it actually works correctly.

The latest version of Gnome-shell starts to display (the top bar appears briefly) but I then get logged out. This happens when I start it with "gnome-shell --replace". Any idea how to make it behave properly? Laptop is a MSI U21, an0d I run with a 'nomodeset' startup option. Without this option the screen clears to just wallpaper and stays that way.

Gnome-shell v2.31.5 Kernel 2.6.35-27 (& 28 as well)

My HP G61 428CA has an unusual problem. Suspend/resume works fine as long as I don't suspend it for longer than 6 or 8 hours. If I do this, it won't wake up ... the keyboard lights flash reporting what the manual describes as a "BIOS corruption". Does anyone know of any tweaks/quirks that I can use to resolve this problem?

When I have my Empathy chat status set to "available", I'd like it to get set to "away" when I lock my computer of the screensaver kicks in. It seems that it stays set to "available" as I frequently have people initiate chats when I'm actually away. I was under the impression that the status control as I desire was supposed to be built in. Is there some configuration option I'm missing? Will I get the behaviour I want if I go back to Pidgin?

I generally set up power hungry servers with a fairly short timeout before they're supposed to suspend or hibernate, but they seem to occasionally go to sleep during file transfers, ssh sessions, etc. What sort of activities are considered "activity" of the sort that will keep the machine awake?

This is on an HP G-61 laptop. Any tips on how to fix the problem? Maverick, but the same problem was there in Lucid ...

I actually just tried this on my MSI Wind, and have the same problem. Basically, I'm installing KDE onto a standard Ubuntu setup using the KDE desktop packages from the repositories, then selecting it manually on the login screen.

After doing an in-place upgrade from Lucid to Maverick, my screen savers no longer work. I get a background that the panel/title-bar image, but no screen saver. I see no messages in dmesg, and don't really know where to start looking for causes for this problem.

I'm hoping I'm not imagining things, but I'm fairly sure that I saw a clean 10.04 install with a key icon displayed in the menu bar. I believe it appeared when sudo was active for updating, etc. I don't seem to have this icon anymore, and I was wondering if it was something I removed inadvertently, or a problem because of the number of upgrades I've done.

If you know of this icon/functionality, please let me know.

I have ufw set up to allow samba connections, but this does not seem to allow files to be transferred through Ubuntu's "Personal File Sharing" using the Public folder. The share can be seen, but not accessed if the firewall is active. Are there extra ports that need to be opened?

The default ufw profile opens ports 137, 138, 139 and 445. To this, I've added 135 and 80, but so far, no joy. I do see connection attempts coming in on high ports (32K+) but these are blocked.

By PS3 Media server, I mean the package, rather than an actual PS3. It's a uPnp server. My XBox can see it and stream from it, but the Coherence plug-in of RhythmBox does not seem to be able to. I suspect it may need a new renderer configuration. Has anyone run into this problem and resolved it? I also had the same problem with x360mediaserver, a similar server side package.

I'm running 10.04, with FireFox 3.6.x. I have NoScript and AdBlock installed, as well as Firebug and the GWT toolkit. The problem I'm having is that sometimes URLS open in new tabs even just with a normal click. I use my laptop's built-in trackpad as a pointing device with 'tap to click' enabled. This seems to happen between 10 and 25% of the time. It's quite annoying. Anyone have any idea what causes this?

That's pretty much it. If I connect to the Internet on wlan0, how can I share this connection with a device plugged into my wired Ethernet port eth0?
