Anyone got three monitors working?
by thomas cameron 04 Jun '12

04 Jun '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Howdy All - I have Gigabyte EP43-UD3L motherboard with a single PCI Express 2.0 x16 slot. It currently has a decent NVidia card - a GeForce 7300 GT. I've got two monitors attached, one via the VGA port and one via the digital video port. It works well, I get accelerated X and wobbly windows and all that silliness. Guilty pleasure: I like eye candy. I'd *really* love to do triple head - the monitor in front of me for my main work, and the two side screens for supporting stuff. I am wondering, since my motherboard has a four PCI Express x1 ports and I see PCI Express x1 video cards for decent prices, if I can either replace my single card with two identical two-port X1 cards, or just add a single X1 video card to what I already have and get triple head. Has anyone done this?

oovoo.com
by Gregory P. Ennis 25 Apr '12

Dear List, I was asked to assist connecting a Fedora linux system for video conferencing with oovoo.com. It is apparent that they support Mac and Windows. Does anyone have any experience in using the Mac installation for oovoo for Fedora? Can anyone make recommendations for connections that allow video conferencing with Fedora. Thanks much -- Greg Ennis PoMec Corporation www.PoMec.net

Gnome-Shell
by David Quigley 09 Mar '12

09 Mar '12

Is there a list anywhere of supported hardware for gnome-shell? I've tried it on 3 computers so far and none of them work. The first was VMWare which I've seen isn't supported so I wrote that off. The second was a dell optiplex 790 with on-board intel accelerated graphics. The final one is an optiplex 960 with a Radeon HD 3450 in it. Is there something wrong with the setup or is gnome-shell really that selective about hardware even after its been in two Fedora releases? Dave

Fedora 16 black screen with Radeon HD 6470M: partially solved?
by M. Fioretti 20 Feb '12

20 Feb '12

Greetings, SHORT VERSION: I think I've found a temporary solution to this Fedora install problem (found on other distros too), but I am not sure about _why_ it works, and it's the best solution. Any feedback is very appreciated. I've got a HP G6 1273SL laptop with this chipset and a live cd of Fedora 16 x86_64, KDE spin. When running live from the CD there were NO graphic problems. So I went and installed it on the laptop hard disk. The install was successful, or so anaconda said, so I rebooted. I got the GRUB 2 menu just fine. However, when I select or let start the default entry, the screen goes completely black. If I remove the "quiet" option in the grub entry I see that the last thing before it goes black is "radeon something..." (too fast to read it...) So it seems to me that is the same issue mentioned here: http://ask.fedoraproject.org/question/179/black-screen-while-startingwhen-f… I have done a bit of research and found this: http://askubuntu.com/questions/28848/what-does-the-kernel-boot-parameter-se… linked from https://answers.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+questi… which also mentions the same problem on Fedora, and indeed, if I enter "e" in grub and add to its initrd line the two parameters acpi_osi=Linux acpi_backlight=vendor Fedora boots without problems, but the laptop is quite warm. This other page says even the first parameter alone is OK: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/765438/comments/2 Now the questions: 1) first of all, I admit I don't really understand how and why this works, that is if this is a real/ complete / best solution. Should I add those two parameters to GRUB_CMDLINE_LINUX_DEFAULT, rerun grub2-mkconfig -o /boot/grub2/grub.cfg and go on? I believe i should also try some combination of vgaswitcheroo and/or radeon.modeset=0 as mentioned in other " Radeon HD 6470M and black linux screen" threads like http://ubuntuforums.org/showthread.php?p=11271523 http://ubuntuforums.org/showthread.php?t=1781662 that, as far as I undertsand, should be better since they should completely turn off that chip and make the laptop cooler but... how to implement them in Fedora? This not clear to me. 2) why there was no problem with the live cd??? What are the options used there that make the distro work from the cd but not from the hard disk? Please note that, for me, at least for the short/medium term, it is perfectly OK for me to use only the on-board graphich chipset instead of the radeon one, I don't need to do heavy 3D stuff with this laptop... Thanks, hope this helps. Marco

F16 unusable while writing to pendrive
by Patrick O'Callaghan 23 Jan '12

23 Jan '12

This looks like a regression. Under F15 when I wrote large files to a pendrive, the system would become a little sluggish. Now it essentially freezes until the write terminates. What I mean is that the UI is almost completely unresponsive; even clicking between two terminal windows is so slow that you can see the window contents refresh, followed several seconds later by the frame. Fully updated F16 with KDE, Intel Core 2 Dual, 4GB RAM, Intel onboard graphics. The pendrive is an 8GB Patriot Xporter (a year or two old) under USB-2 with no intervening hub. poc

ld finds some libraries, but not others.
by Jonathan Ryshpan 22 Jan '12

22 Jan '12

A build is failing with the error cannot find <library> for libraries that are, in fact present on the system. I made a very simple test bed, consisting of the empty file conftest.c, which I attempt to compile and link with various libraries. All the libraries are in /usr/lib64. Sometimes the compilation fails with undefined reference to `main' which is what I would expect, but often it fails with cannot find -l<whatever> I have no idea what's happening. Can anyone explain? Here's an example of what's going on. This is a listing of some files in /usr/lib64: 1167 lib64 $ ll libICE.so* libgd.so* libkate.so* libkblog.so.* lrwxrwxrwx. 1 root root 15 Nov 9 18:28 libICE.so -> libICE.so.6.3.0* lrwxrwxrwx. 1 root root 15 Nov 9 08:02 libICE.so.6 -> libICE.so.6.3.0* -rwxr-xr-x. 1 root root 98328 Jun 21 09:37 libICE.so.6.3.0* lrwxrwxrwx. 1 root root 14 Nov 9 08:14 libgd.so.2 -> libgd.so.2.0.0* -rwxr-xr-x. 1 root root 278048 Oct 26 20:15 libgd.so.2.0.0* lrwxrwxrwx. 1 root root 16 Nov 9 08:06 libkate.so.1 -> libkate.so.1.2.1* -rwxr-xr-x. 1 root root 75640 Mar 7 2011 libkate.so.1.2.1* lrwxrwxrwx. 1 root root 17 Nov 13 09:03 libkblog.so.4 -> libkblog.so.4.7.0* -rwxr-xr-x. 1 root root 312960 Nov 4 10:05 libkblog.so.4.7.0* And here's a attempt to compile the dummy linking to them: 1033 wview-5.19.0 $ gcc -o conftest -g -O2 conftest.c -lICE /usr/lib/gcc/x86_64-redhat-linux/4.6.2/../../../../lib64/crt1.o: In function `_start': (.text+0x20): undefined reference to `main' collect2: ld returned 1 exit status 1034 wview-5.19.0 $ gcc -o conftest -g -O2 conftest.c -lgd /usr/bin/ld: cannot find -lgd collect2: ld returned 1 exit status 1035 wview-5.19.0 $ gcc -o conftest -g -O2 conftest.c -lkate /usr/bin/ld: cannot find -lkate collect2: ld returned 1 exit status 1036 wview-5.19.0 $ gcc -o conftest -g -O2 conftest.c -lkblog /usr/lib/gcc/x86_64-redhat-linux/4.6.2/../../../../lib64/crt1.o: In function `_start': (.text+0x20): undefined reference to `main' collect2: ld returned 1 exit status

Question on shredding a terebyte drive
by Dean S. Messing 16 Jan '12

16 Jan '12

I have a terebyte sata drive that I need to securely wipe clean. It originally had 2 partitions. I deleted them using `fdisk', rebooted, and then as root ran shred -vz /dev/sdd The drive is capable of about 60MB/sec, but shred is only "shredding" about 25MB every 5 seconds according to its output. Since the default number of passes is 25, this works out to about 5 days. The `shred' process is running at 100% CPU, presumably computing the special random patterns for erasure. Since I have 4 CPUs would creating 4 unformatted partions on the drive and then running something like: shred -vz /dev/sdd1 shred -vz /dev/sdd2 shred -vz /dev/sdd3 shred -vz /dev/sdd4 in parallel cut my time? Would be just as secure? Thanks Dean

OT: How much RAM should I get in a new laptop ?
by linux guy 13 Jan '12

13 Jan '12

I'm specing a new laptop, probably a Dell XPS 17, with an i7 processor. It will have an SSD and be driving 2 monitors. The XPS 17s come in two varieties, one with 2 DIMM slots and the other with 4 DIMM slots. - I do a ton of browsing for research purposes and may have as many as 20 Firefox sessions open at one time. - I use Thunderbird with mail accounts with more than 100K messages in them. - I do some software development in Eclipse with gcc. Compile times can be lengthy on some projects. - I use Digikam to manage and edit all my Nikon D7000 images, which are shot in raw - I want to get into editing D7000 video files - I want to get into 3D CAD. How much RAM do I reasonably require ? Is it worth paying more for 4 DIMM sockets over 2 ? Thanks !

Printer detection in Fedora
by Fred Smith 12 Jan '12

12 Jan '12

Hi all! Just a note to throw out here, in case Tim W. or anyone else finds the information helpful. I have, until earlier this year, run Fedora on my eeepc 901. When F15 came out I played with it as a live CD and didn't really like the gnome changes, so I've moved on to other Linuxen. But my purpose in posting here: as late as F14 and F15, when I'm given to understand the printer configuration tools should be able to autodetect and configure most printers, I found that for my Brother HL-2070N I needed to manually configure it. why? well,... the "new printer" option in the printer setup utility (is it system-printer-config ???) would never figure out what kind of printer it was even if it did otherwise find it out there on the LAN. I figured it was just one of those printers that didn't announce itself with enough detail for the system to auto-config. Well, time goes by and I try playing with a Linux-Mint 12 live cd, and to my astonishment I find that when I choose to add a new printer, I dont' have to enter ANY settings, it "just works". Note that I HAVE NOT tried using F16 to configure this printer on this netbook, perhaps it works just as well, now, as does Linux-Mint 12, I dunno. But certainly Mint gives me a better experience, in this regard, than did F14 or F15. Consider this just a note to offer a suggestion on where you may be able to look to find out more of how some printers can be diagnosed successfully, in case you've not already achieved this in the latest versions. And even though I"m not currently using Fedora, I appreciate all the work you guys have done, and still think Fedora is a great distribution. Thanks muchly!
