[opensuse] nomachine nxclient on SuSE 11.1 doesn't work
by Lance Drager 01 Apr '09

Has anyone been able to get the nxclient from www.nomachine.com to work on SuSE 11.1 I get Xlib: connection to ":0.0" refused by server Xlib: No protocol specified nxclient: cannot connect to X server :0.0 Alternatively, has anyone gotten freenx-client to work? If so, how? Lance Drager

[opensuse] mdraid 1 - is one driver primary for read/write, then sync mirrors?
by David C. Rankin 01 Apr '09

01 Apr '09

Listmates, Looking at hdparm -tT results for a Linux Software raid 1 array, I see some differences in the read performance that I don't know whether it is just individual drive difference or whether mdraid may have something to do with it. The mdraid 1 setup is on a pair of 750G Seagate drives: /dev/sdb: ST3750330AS: 34°C /dev/sdc: ST3750330AS: 36°C The raid1 devices are /dev/sdb1 and /dev/sdc1 which take up the entire disk on each. I don't know if there is a reason not to use the whole drive in the array, but the array is basically a temporary setup on my sons computer (with open SATA port) to throw the drives in to get a week or so of runtime on them before moving them over to a server. Checking read performance with hdparm of each individual drive and then of the array itself shows a small performance difference/drop for /dev/sdc: 02:11 KillerZ~> for i in sdb sdc md0; do sudo hdparm -tT /dev/$i; done /dev/sdb: Timing cached reads: 2130 MB in 2.00 seconds = 1064.71 MB/sec Timing buffered disk reads: 328 MB in 3.01 seconds = 108.94 MB/sec /dev/sdc: Timing cached reads: 2088 MB in 2.00 seconds = 1044.08 MB/sec Timing buffered disk reads: 292 MB in 3.02 seconds = 96.84 MB/sec /dev/md0: Timing cached reads: 2116 MB in 2.00 seconds = 1057.94 MB/sec Timing buffered disk reads: 322 MB in 3.01 seconds = 107.13 MB/sec Thinking about it (dangerous thing to do) the questions arose of (1) how does mdraid actually work, is there a primary drive that is uses for read/write while the other is there for sync/backup? (2) If you can't write simultaneously to both at the same time using the same clock cycle (can you??) so somewhere it seems there must be a write/copy function in the mdraid scheme, and if the drives are slaved together by my the data in mdadm.conf, could the read performance difference being seen with /dev/sdc above be the result of mdraid function and not simply a drive variance? I haven't a clue, that's why I'm asking. And then there is the /dev/md0 hdparm performance which looks like it takes the better of the two performance stats, less a tiny amount of mdraid overhead. How does that work? Or is the difference there more of a simple weighted averaging of the drive performance between sdb and sdc?? Any software raid gurus willing to shed a bit of light on this situation. -- David C. Rankin, J.D.,P.E.

[opensuse] Suse 11.1 Monitor Resolutions
by Dave Feustel 01 Apr '09

01 Apr '09

I'm currently running Suse 11.0 using a monitor capable of 1440x900. But there is not support for 1440x900, so I have been running the monitor at 1280x768. Does Suse 11.1 support 1440x900 resolution? Thanks. -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

[opensuse] Stubborn screen blanking under OS11.1
by JC Francois 01 Apr '09

01 Apr '09

Hi, For a few weeks now my OpenSUSE 11.1 desktop PC has arbitrarily decided to blank the screen after 6 minutes of inactivity. Nothing that I have tried so far has managed to modify this behaviour. I tried: * disabling screensaver * under > Configure Desktop > Advanced > Power Management Assign the same profile to all scenarios and disable screen power management for that profile * Using SaX2 to modify DPMS settings but Sax2 keeps reporting circular syntax errors in xorg.conf when trying to save so I gave up. * editing xorg.conf to set Option "DPMS" to "false" I saw this issue brought up in the past on the forum and this mailing list but no solution was provided so I am taking my chance.

[opensuse] Xen paravirtualized guest upgrade problems
by Peter Sjoberg 01 Apr '09

01 Apr '09

I have two systems running OpenSuSE 10.3 as xen host and a few guests. I like to upgrade everything to latest OpenSuse 11.1 but bumped in to problems. I managed to get the host upgraded but when it comes to a paravirtualized guest I don't know where to start. Googled a bit and the closest I got was to use "zypper dup" but for me it was more errors then I can handle so I don't think that's the way to go. Boot CD won't work since the cd doesn't have a paravirtualized kernel I might be able to wing something together for a network boot but don't know where to start. Is there any recommended way to move a 10.3 environment to 11.1 (besides reinstall) ? -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

Before 3.0.1, I used to be able to add &nbsp to an html doc by using Ctrl+Space. What do I use now. I looked in Help but could not find it - unless I missed ti.
