    - by SDD
    I am using: - Linux Mint 11 - Geforce 560ti - nVidia driver (installed via helper programm, not from nvidia page) The third party nvidia drivers radomly cause very poor 2D performance. Radomly because the performance can be very great, but after the next reboot or login become very poor. After another reboot or login, this might change again to better or worse. I have no idea why and how and I need your help. Thank you.

  • System Event ID 11 Disk

    - by Guy Thomas
    Upon starting Windows Server 2008 R2 I get this error message: Event ID 11 Disk The driver detected a controller error on \Device\Harddisk3\DR3. There are also also 3 more similar messages for Harddisk 2, 4, and 5, but not zero or 1. Checking the event viewer reveals it's been going on for 3 months. I ran chkdsk - no bad sectors. Any advice on the cause, better still, a solution?

  • What driver for M1015 for Solaris 11 Express

    - by Garuda
    For Solaris 11 Express, what driver is supposed to be used? The M1015 is essentially a LSI 9240-8i From http://www.lsi.com/products/storagecomponents/Pages/MegaRAIDSAS9240-8i.aspx The only driver for Solaris is a old 32bit driver? I'd like to Flash it also, but can't seem to figure out which util to use.. The linux one from IBM screams for libraries that aren't included in the libraries section.

  • IPS Package Groups

    - by Alan_Solaris_RE
    IPS group packages consist solely of dependencies on other packages that make up a logical grouping of software. These are similar to, but not the equivalent of, Solaris 10 metaclusters. The main difference is that metaclusters are nested subsets ranging from a minimal install to nearly all packages on the media. Group packages have no such hierarchy. They can overlap other groups, or be completely disjoint sets. A group dependency is set this way in an IPS package manifest file: depend fmri=full/pkg/name type=group Current Solaris Groups Solaris currently has 4 system groups defined. These are used for different types of installation, and are included in the xml manifest files used by the various Solaris installers: Package Name Summary Description Default Installation For:  group/system/solaris-desktop Oracle Solaris Desktop Provides an Oracle Solaris desktop environment Live Media  group/system/solaris-large-server Oracle Solaris Large Server Provides an Oracle Solaris large server environment Text Installer  group/system/solaris-small-server Oracle Solaris Small Server Provides a useful command-line Oracle Solaris environment  Zones  group/system/solaris-auto-install  Oracle Solaris Automated Installer Client  Provides an Oracle Solaris Automated Installer client  Automated Installer There are also several "feature" groups such as AMP and GNU Developer Tools. These are provided for convenience, but are not used directly by any installers. Retrieving Group Package Information A listing of all current groups can be found with the command: pkg info -r group/* A listing of all the packages in a group can be obtained with: pkg contents -o fmri -H -rt depend -a type=group groupname An example: $ pkg contents -o fmri -H -rt depend -a type=group solaris-desktop archiver/gnu-tar audio/audio-utilities codec/flac codec/libtheora codec/ogg-vorbis codec/speex communication/im/pidgin etc. You can determine which package group is currently installed on your system: $ pkg list group/system/\* Output would look like: NAME (PUBLISHER) VERSION IFO group/system/solaris-desktop 0.5.11-0.175.0.0.0.0.0 i-- Note that there are not version numbers associated with a group package dependency. The package version that best fits the system will be used, based on other dependencies such as what is listed in incorporation files. Installing a Group To Install a group, simple use the group package name as you would any other package: $ pkg install solaris-small-server  If you want to exclude a package from installing, you can use the --reject flag: $ pkg install --reject audio/audio-utilities solaris-desktop Creating Your Own Group To create your own group package, you can follow the pkg(5) documentation on how to create a package, and use this action for each package that is part of your group:   depend fmri=full/pkg/name type=group

  • Fedora 13 - No module named yum

    - by drozzy
    This is driving me bananas! After a recent update in Fedora 13 64bit, my yum is gone: $> yum update There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: No module named yum Please install a package which provides this module, or verify that the module is installed correctly. I tried looking for an RPM yum package - to install yum. I went to the Fedora site: http://fedoraproject.org/wiki/Tools/yum Call me blind but I cannot find it anywhere on that page! Most of the solutions suggest repairing yum... with yum! But I don't have yum? Yum yum yum? :< Any help? Here are some outputs for rpm commands: $> rpm -ql python | grep "site-packages$" /usr/lib/python2.6/site-packages /usr/lib64/python2.6/site-packages $> rpm -ql yum | grep "site-packages/yum$" /usr/lib/python2.6/site-packages/yum

  • Munin node not listing any plugins on new Fedora 14 installation

    - by Dave Forgac
    I have just installed munin-node from the base repo on Fedora 14 and then started it. I found that my munin server is not able to collect data from this node so I tried connecting via telnet to test. When connecting via telnet I see that no plugins are listed: [dave@host ~]# telnet localhost 4949 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. # munin node at host.example.com list quit Connection closed by foreign host. [dave@host ~]# I did not modify anything after the installation. The munin-node.conf is allowing connections from 127.0.0.1 and the default set of plugins in /etc/munin/plugins/ are symlinked to the plugins in /usr/share/munin/plugins/. Here is the working output of the telnet test of the 'list' command should look like (this is on a Fedora 13 host): [dave@www ~]$ telnet localhost 4949 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. # munin node at www.example.com list apache_accesses apache_processes apache_volume cpu df df_inode entropy forks fw_packets if_err_eth0 if_err_eth1 if_eth0 if_eth1 interrupts iostat iostat_ios irqstats load memory munin_stats mysql_ mysql_bytes mysql_innodb mysql_queries mysql_slowqueries mysql_threads netstat open_files open_inodes postfix_mailqueue postfix_mailvolume proc_pri processes swap threads uptime users vmstat yum quit Connection closed by foreign host.

  • Fedora 17 - Dropping into debug shell after attempted partitioning

    - by i.h4d35
    So I tried creating a new partition on Fedora 17 using fdisk as follows: Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (2048-823215039, default 2048): Using default value 2048 Last cylinder or +size or +sizeM or +sizeK (1-9039, default 9039): +15G Once this was done,instead of formatting the partition I created, I ran the partprobe command to write the changes to the partition table. On rebooting the computer, it drops to the debug shell and gives me the error as follows: dracut warning:unable to process initqueue dracut warning:/dev/disk/by-uuid/vg_mymachine does not exist dropping to debug shell dracut:/# While trying to run fsck on the said partition from the debug shell, it says "etc/fstab not found" and inside /etc I see a fstab.empty file. Is it now possible to retrieve what I have from the computer? Any help would be appreciated. Thanks in advance Edit: I've also tried the following steps for additional troubleshooting: I tried to boot using the Fedora disk and tried the rescue mode - says no Linux partition detected. I tried to create an fstab file by combining the entries from blkid and the /etc/mtab file and using the UUIDs from the mtab file - It didn't work. As soon as I rebooted the machine, it promptly dropped me in to the debug shell and the fstab file which i created wansn't there anymore in /etc (part of this solution)

  • Identifying Httpd error log in Fedora 16

  • OpenSwan (IPSEC) on Fedora 13 with Snow Leopard as a client

    - by sicn
    I recently installed OpenSwan on my Fedora 13 machine. I want to use it to connect with Mac OS X with L2TP over IPSEC, unfortunately I am already stuck on the IPSEC-negotation part. My server is running behind a NATted firewall so my external IP differs from the server's IP. The server has a fixed IP on the network and the same is almost always valid for the clients (they are usually behind a NATted firewall). I installed OpenSwan on Fedora 13 and have following configuration: config setup protostack=netkey nat_traversal=yes virtual_private=%v4:10.0.0.0/8,%v4:192.168.0.0/16,%v4:172.16.0.0/12 oe=off nhelpers=0 conn L2TP-PSK-NAT rightsubnet=vhost:%priv also=L2TP-PSK-noNAT conn L2TP-PSK-noNAT authby=secret pfs=no auto=add keyingtries=3 rekey=no ikelifetime=8h keylife=1h type=transport left=my.servers.external.ip leftprotoport=17/1701 right=%any rightprotoport=17/0 IPSEC starts fine and listens to UDP 500 and 4500. These two ports are opened in the firewall and are forwarded fine to the server. In my /etc/ipsec.secrets file I have my.servers.external.ip %any: "LongAndDifficultPassword" And finally in my sysctl.conf (the redirect-entries are there because OpenSwan was strongly protesting about send/accept_redirects being active) I have net.ipv4.ip_forward = 1 net.ipv4.conf.all.send_redirects = 0 net.ipv4.conf.all.accept_redirects = 0 Running "ipsec verify" gives me "all greens" (except Opportunistic Encryption Support, which is DISABLED), however, when trying to connect my Mac gives me following in the logs: Nov 1 19:30:28 macbook pppd[4904]: pppd 2.4.2 (Apple version 412.3) started by user, uid 1011 Nov 1 19:30:28 macbook pppd[4904]: L2TP connecting to server 'my.servers.ip.address' (my.servers.ip.address)...

  • lighttpd on Fedora permission issues

    - by Isaac Gateno
    I'm trying to get started with lighttpd on Fedora 16 to run a RESTful api for development. Right now even with the most basic sample config file I'm getting 404 pages when I know the pages I'm pointing at exist. From reading other questions I'm leaning towards this being a permissions issue, but I'm confused about how lighttpd runs on Fedora. There's a user called "lighttpd" not "www-data"? I can't see this user in the system-config-users tool and I can't su into it to check which permissions it has. I'm trying to point lighttpd to "/var/www/lighttpd" which has some example pages in it. The permissions for the files inside are set to -rw-r--r-- and the permissions for the folder containing them are drwxr-xr-x. Doesn't that mean that any user can view these files? I'm not sure what else I should be checking as I don't have much experience with server configuration. Any help would be appreciated. Edit: I was following the tutorial configuration here so the lighttpd.conf file contains server.document-root = "/var/www/lighttpd/" server.port = 3000 mimetype.assign = ( ".html" => "text/html", ".txt" => "text/plain", ".jpg" => "image/jpeg", ".png" => "image/png" ) and I was just trying to get the basic example page working.

  • Installing a clean Python 2.6 on SuSE (SLES) 11 using system-wide libraries

    - by optilude
    Hi, I've spent most of the day on this, and it is driving me absolutely insane. On all other Unixes I've used, this is a walk in the park, but SLES 11 has me dumbfounded. I need to build Zope on SLES 11 64 bit: Linux <name> 2.6.27.45-0.1-default #1 SMP 2010-02-22 16:49:47 +0100 x86_64 x86_64 x86_64 GNU/Linux I first tried to just use the YaST-installed Python 2.6. I've also installed python-devel, libjpeg-devel, readline-devel, libopenssl-devel, libz2-devel, zlib-devel, and libgcrypt-devel. The global python2.6 has a lot of cruft in it, and seems to execute stuff in /etc/pythonstart when I use it, which doesn't help. However, the error I get is this: Getting distribution for 'Zope2==2.12.3'. src/AccessControl/cAccessControl.c:596: warning: initialization from incompatible pointer type src/AccessControl/cAccessControl.c:598: warning: ‘intargfunc’ is deprecated src/AccessControl/cAccessControl.c:598: warning: initialization from incompatible pointer type src/AccessControl/cAccessControl.c:599: warning: ‘intargfunc’ is deprecated src/AccessControl/cAccessControl.c:599: warning: initialization from incompatible pointer type src/AccessControl/cAccessControl.c:600: warning: ‘intintargfunc’ is deprecated src/AccessControl/cAccessControl.c:600: warning: initialization from incompatible pointer type src/AccessControl/cAccessControl.c:601: warning: initialization from incompatible pointer type src/AccessControl/cAccessControl.c:602: warning: initialization from incompatible pointer type src/AccessControl/cAccessControl.c:606: warning: ‘intargfunc’ is deprecated src/AccessControl/cAccessControl.c:606: warning: initialization from incompatible pointer type /usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../x86_64-suse-linux/bin/ld: skipping incompatible /usr/lib/libpython2.6.so when searching for -lpython2.6 /usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../x86_64-suse-linux/bin/ld: cannot find -lpython2.6 collect2: ld returned 1 exit status error: Setup script exited with error: command 'gcc' failed with exit status 1 An error occured when trying to install Zope2 2.12.3. Look above this message for any errors that were output by easy_install. I don't know what "incompatible" is referring to here; my guess would be the hardware architecture, but I'm not sure what's incompatible with what in the statement above. I've had problems with system-installed Pythons before, so I tried to compile my own (hence the list of -devel packages above), downloading the Python 2.6 tarball and running: ./configure --disable-tk --prefix=${HOME}/python make make install This installs, but it seems to be unable to find any system-wide libraries.

  • Creating a voxel world with 3D arrays using threads

    - by Sean M.
    I am making a voxel game (a bit like Minecraft) in C++(11), and I've come across an issue with creating a world efficiently. In my program, I have a World class, which holds a 3D array of Region class pointers. When I initialize the world, I give it a width, height, and depth so it knows how large of a world to create. Each Region is split up into a 32x32x32 area of blocks, so as you may guess, it takes a while to initialize the world once the world gets to be above 8x4x8 Regions. In order to alleviate this issue, I thought that using threads to generate different levels of the world concurrently would make it go faster. Having not used threads much before this, and being still relatively new to C++, I'm not entirely sure how to go about implementing one thread per level (level being a xz plane with a height of 1), when there is a variable number of levels. I tried this: for(int i = 0; i < height; i++) { std::thread th(std::bind(&World::load, this, width, height, depth)); th.join(); } Where load() just loads all Regions at height "height". But that executes the threads one at a time (which makes sense, looking back), and that of course takes as long as generating all Regions in one loop. I then tried: std::thread t1(std::bind(&World::load, this, w, h1, h2 - 1, d)); std::thread t2(std::bind(&World::load, this, w, h2, h3 - 1, d)); std::thread t3(std::bind(&World::load, this, w, h3, h4 - 1, d)); std::thread t4(std::bind(&World::load, this, w, h4, h - 1, d)); t1.join(); t2.join(); t3.join(); t4.join(); This works in that the world loads about 3-3.5 times faster, but this forces the height to be a multiple of 4, and it also gives the same exact VAO object to every single Region, which need individual VAOs in order to render properly. The VAO of each Region is set in the constructor, so I'm assuming that somehow the VAO number is not thread safe or something (again, unfamiliar with threads). So basically, my question is two one-part: How to I implement a variable number of threads that all execute at the same time, and force the main thread to wait for them using join() without stopping the other threads? How do I make the VAO objects thread safe, so when a bunch of Regions are being created at the same time across multiple threads, they don't all get the exact same VAO? Turns out it has to do with GL contexts not working across multiple threads. I moved the VAO/VBO creation back to the main thread. Fixed! Here is the code for block.h/.cpp, region.h/.cpp, and CVBObject.h/.cpp which controls VBOs and VAOs, in case you need it. If you need to see anything else just ask. EDIT: Also, I'd prefer not to have answers that are like "you should have used boost". I'm trying to do this without boost to get used to threads before moving onto other libraries.
