Wireless transfer throughput?
by mike cloaked 22 Dec '08

22 Dec '08

I wonder if anyone can explain to me why the achieved throughput for an rsync transfer for files across a wireless connection should be different than I expect as I try to explain below? The situation is that I have a local LAN over which I can run a transfer from two different laptops to a wired only desktop machine on which I keep backup files. The two laptops have different wired and wireless NICs. On the wired connection on a 10/100 system I get file transfers down the wire to the desktop at about 11.7MB/s as measured on the gnome netspeed applet, which is about what I would expect since this is around 95mbps and I could easily imagine a 5% loss for TCP overheads. This is the same for both laptops. On the first laptop if I do file transfers via wireless through its iwl3945 wireless card then I get an achieved throughput through my AP using WPA2 encryption at around 0.75 MB/s which corresponds to about 6mbps - and this is on a link which the laptop system tells me is connected at 54mbps. The machine is a few feet from the AP and shows a 100% signal. On the second laptop which runs an iwl4965 wireless card I get around 1.5MB/s, corresponding to about 12mbps for the same conditions. All machines are running F10, but these speeds were the same for F8 before I did clean F10 installs on them all, so the specific version of Fedora seems to be irrelevant here. The way I look at what speeds I would expect is that I would imagine a roughly (estimated) 50% loss due to the WPA2 encryption, so I would hope to see around 27mbps, which corresponds to just over 3 MB/s. So I am seeing a 50% loss roughly on the machine running iwl4965 and another factor of two or so on the machine running iwl3945. Is this a problem with drivers or have I done my maths wrong? The machines are running the stock kernel and drivers and currently am running NetworkManager, though previously I was using wpa_supplicant directly. Either way these details seemed not to change the numbers. Any thoughts on this? I would be interested in being educated about this. -- View this message in context: http://www.nabble.com/Wireless-transfer-throughput--tp21134634p21134634.html Sent from the Fedora List mailing list archive at Nabble.com.

lost compiz Decrease window opacity with new update
by Hugh Caley 22 Dec '08

22 Dec '08

Before today I was able to decrease the opacity of individual windows by holding down the alt key and running my scroll wheel back. After the update today I could no longer do that. I installed gnome-compiz-preferences and the Decrease window opacity field was empty. I clicked in it, and held alt and my scroll wheel (actually evidently botton 5 on my Logitech marble mouse) and now it says <Alt>Button5 but it still doesn't do anything. Swinging the desktops around and wobbly windows still work. I do get an error with gnome-compiz-preferences; 3 of these: "Type mismatch: Expected list, got string" -- Hugh Caley, Linux Administrator Aldon Computer Group 6001 Shellmound St. Suite 600 Emeryville, CA 94608 (510) 285-8542 | hughc(a)aldon.com

Rdeskt issue under Compiz w/ KDE
by Joseph L. Casale 22 Dec '08

22 Dec '08

So after yesterdays Compiz updates, now when I Alt-Ctrl-Enter an rdesktop window started in full screen, it flashes briefly to a window a re-fullscreens again? The only way to exit it is to Alt-Ctrl-Enter while pushing the mouse to the upper corner so I can engage the window selector and choose another app so that rdesktop is forced to a window... jlc

Call for vote: Nautilus use Browser view for fedora 11
by Mark 22 Dec '08

22 Dec '08

Hey, The question is simple: Lets use the browser view of nautilus in the next fedora release. Motivation: A new window for each folder that i open is so painful!! 1. My taskbar fills up in notime each time i open a new folder 2. New features of nautilus: tabbed browsing! completely useless if your not using the browser mode 3. Tabbed browsing (files/folders or web) is "hot" these days 4. It feels so.. old (windows 95? 3.11?) just to name a few Cross posted to the devel list because it's for the next fedora version (currently in development thus the devel list) Bug report: https://bugzilla.redhat.com/show_bug.cgi?id=477052 (wow! i couldn't find an existing one for this! made one myself) So, lets vote: +1 from me I hope this can be done for Fedora 11 (it's just changing one gconf value). All vote plz Mark.

Deactivating password request after screen lock
by Weiner, Michael 22 Dec '08

22 Dec '08

I have an unusual request from a user that I support, who would like me to deactivate (or disable) the password request that occurs after the screen is locked in an X session. He runs KDE and when the session is inactive, it locks the screen (as normal). And when he returns he finds it annoying to be asked for his password in order to unlock the screen. After a short period of explaining why this was a security FEATURE of the system, he still insists on having me do this. I have googled for some time and have come up empty handed and was wondering if ANYONE on this list had ever done this and how.

I have used KDE 3.x for many years and appreciated it for its features, its stability, its extremely-good configurability, and its many "techie" features which prefer. KDE 4.1 so far has lost many of the features and much of the configurability of the 3.x releases, and I'm waiting to see whether 4.2 restores enough of them to make it a viable desktop. I use my computer to (a) develop code and systems, (b) manage multiple machines and networks, (c) experiment with clustering and parallel processing. So no matter how beautiful it is, if KDE4.x continues to lack the features I actually _need_ on a daily basis, I'll probably switch desktops - either back to Gnome or to another wm. I don't like (and won't participate in) flame wars, but I have to say that while some things are better in KDE 4.1 than under KDE3.x, for my purposes the missing features far outweigh the improvements. As someone said, perhaps by 4.2, 4.3, etc., things will improve - but since I have to use the machine _now_, those are not currently options for me. -- william w. austin waustin(a)speakeasy.net "life is just another phase i'm going through. this time, anyway ..."

Xserver resolution changes
by Ernesto Silva 22 Dec '08

22 Dec '08

Hi, I'm new to this list and I've "googled" a bit about an issue but I can't find the answer, so here it is: I'm running fedora 9 with Gnome and everything works fine. I've also tried Blackbox, twm and WindowMaker windows managers and the screen resolution it's not the same as in Gnome, I can't understand why. Obviously when I start Blackbox or twm or WindowMaker the resolution is worst than with Gnome. In Gnome I have 1280x720 and in the others I have 1024x768. Here is my xorg.conf file # Xorg configuration created by system-config-display Section "ServerLayout" Identifier "single head configuration" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "InputDevice" # keyboard added by rhpxl Identifier "Keyboard0" Driver "kbd" Option "XkbModel" "pc105" Option "XkbLayout" "us" EndSection Section "Device" Identifier "Videocard0" Driver "intel" EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection Any Ideas? Regars, Ernesto Silva.
