  • How to disable monitor "sleep" on Ubuntu without access to X?

    - by exhuma
    I just received a CuBox (basically a tiny ARM based PC). It comes pre-installed with Ubuntu, and I did not (yet) want to fiddle with the OS itself. My aim is to have it automaticall start a browser in fullscrren upon boot. Using chromium with the "--kiosk" flag works perfectly in that regard. But now I have the problem that the screen turns off after a certain time. I managed to turn off the screen saver using: gconftool-2 -s /apps/gnome-screensaver/idle_activation_enabled --type=bool false And tried to turn off the power management using: gconftool-2 -s /apps/gnome-power-manager/ac_sleep_display --type=int 0 and gconftool-2 -s /apps/gnome-power-manager/timeout/sleep_display_ac --type=int 0 Neither of the power-management commands worked. Theoretically I could hook up a mouse and keyboard and configure it manually. But I want to learn how to do it over the console. The box will eventually be only reachable via SSH. So I'd like to be able to trouble-shoot it later. I don't quite know where to look for. I searched the gconf tree using gconftool-2 -S for anything related to the terms power, idle and sleep but did not find anything promising. Maybe it's not even gconf related... Any ideas what else I could look for?

  • Nginx Ubuntu Postfix Config - Can't connect to incoming IMAP server 'server not responding' but can send mail via outgoing using same details?

    - by daveaspinall
    I'm pretty to new server admin and especially nginx but seem to be getting ok fine apart from accessing my mail via my iPhone? I've changed my domain to 'domain.com' The thing is I can send mail via my outgoing IMAP server but can't connect to the incoming one? I just get the message "the mail server at mail.domain.com is not responding" /etc/postfix/main.cf alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no biff = no broken_sasl_auth_clients = yes config_directory = /etc/postfix home_mailbox = Maildir/ inet_interfaces = all inet_protocols = all mailbox_command = mailbox_size_limit = 0 mydestination = domain.com, mail.domain.com, localhost.com, , localhost, localhost.localdomain mydomain = domain.com myhostname = mail.domain.com mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 myorigin = /etc/mailname recipient_delimiter = + relayhost = smtp_tls_note_starttls_offer = yes smtp_tls_security_level = may smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = smtpd_sasl_security_options = noanonymous smtpd_tls_CAfile = /etc/ssl/certs/cacert.pem smtpd_tls_auth_only = no smtpd_tls_cert_file = /etc/ssl/certs/smtpd.crt smtpd_tls_key_file = /etc/ssl/private/smtpd.key smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_security_level = may smtpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom telnet localhost 25 ehlo locahost 250-mail.domain.com 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-AUTH LOGIN PLAIN 250-AUTH=LOGIN PLAIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN Using the following details to connect: username password hostname: mail.domain.com port: 25 iptables --list Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination I also sent mail to the server as a test and got this missage if it helps? Technical details of temporary failure: [mail.domain.com. (10): Connection refused] I also looked in /var/log/mail.log and it has multiple entries of: postfix/smtpd[12239]: connect from 5acefc9a.bb.sky.com[90.206.252.xxx] Mar 23 06:47:09 new-domain postfix/smtpd[12239]: lost connection after CONNECT from 5acefc9a.bb.sky.com[90.206.252.154] Notice new-domain which is incorrect but the server hostname and hostname in the configs are correct? I recently moves servers and the host has set the primary domain on the service as new-domain.com so this may be the issue? Like I said, it works to connect to outgoing server, but incoming gets the not responding error? Any idea would be much appreciated!

  • Issue with SSH on Ubuntu - Local connection ok, remote connection - Is it me or my ISP?

    - by Benjamin
    I have an issue with a server running Ubuntu 12.04, I am trying to set up a remote connection so I can access the server at my work from out of town. I have installed the SSH server and all that stuff, and I have reassigned the default port from 22 to 3399. A local connection from any OS can connect on the 192.168... address, but in no way can I get a connection on the actual IP address. I believe my configuration is correct, and I will attach it. If I have done something wrong in the config, please tell me and I will make a change to it. I honestly think that the Router that my ISP provided is horrible, and although the port for ssh is forwarded, it might be stopping any traffic coming inbound. Is there anything I can try to verify this? /var/log/auth does not show any error when I connect VIA our static IP. I have included all values not commented out below: (sshd_config) Port 3399 ListenAddress 0.0.0.0 Protocol 2 HostKey /etc/ssh/ssh_host_rsa_key HostKey /etc/ssh/ssh_host_dsa_key HostKey /etc/ssh/ssh_host_ecdsa_key UsePrivilegeSeparation yes KeyRegenerationInterval 3600 ServerKeyBits 768 SyslogFacility AUTH LogLevel INFO LoginGraceTime 120 PermitRootLogin yes StrictModes yes UseDNS no RSAAuthentication yes IgnoreRhosts yes RhostsRSAAuthentication no HostbasedAuthentication no PermitEmptyPasswords no ChallengeResponseAuthentication no PasswordAuthentication yes GSSAPIAuthentication no X11Forwarding yes X11DisplayOffset 10 PrintMotd no PrintLastLog yes TCPKeepAlive yes AcceptEnv LANG LC_* Subsystem sftp /usr/lib/openssh/sftp-server UsePAM yes Am I doing this wrong? port forwarding image

  • How to make Firefox file associations consistent with Ubuntu file associations?

    - by wbharding
    This seems to be a pretty commonly Google question, but one for which there are no answers. http://www.linuxquestions.org/questions/linux-software-2/firefox-download-mime-types-378902 http://www.birkit.com/content/kubuntu-linux/internet/firefox/fix-file-associations-in-firefox.html Being three links amongst the many. The gist of what I want to accomplish is to have Firefox understand the file associations I download without me having to manually map all of them myself. Gnome knows the file extensions, so I would have expected that Firefox could just use the already-known file mappings there to open the right stuff (as I presume Chrome does). But it doesn't. At least not for me, using Firefox 4, and not by default. When I click on a downloaded file right now, Firefox always has to ask me what application should be used to open the file. A handful of Google results tell me that I can reassociate my file extensions by deleting ~/.mozilla/firefox/[profile name]/mimeTypes.rdf, but while deleting that file does in fact result in a new mimeTypes file being generated, the new mimeTypes is just as barren as the old one had been. Based on the amount of unanswered Qs on the Googlesphere, I know this is a very common problem for Ubuntu users, but it seems to be one for which nobody has chimed in with a good solution. Maybe Superuser can finally be the panacea for us all?

  • How do I set up Grub properly to quad-boot Windows, Mac OS X, Linux, and FreeBSD?

    - by Joe
    Grub has gone completely insane on me. My quad-boot system was working great up until I upgraded Ubuntu to 12.04. Since Ubuntu overwrote the Grub stuff I had to repair it with my Mac OS X and FreeBSD entries. After this, trying to boot Mac OS X gave me the error "couldn't open file" and FreeBSD gave the error "no such partition". Windows and Ubuntu worked fine. So I tried repairing again because I figured something must've gone wrong in the install process. Then only Ubuntu would boot. Trying to boot Windows would give me the error "no argument specified". I tried repairing Grub once again, since I seemed to be getting different results each time. This time, Ubuntu no longer appeared in the Grub menu, and the errors for the other OSes were the same. So I booted into the Ubuntu 12.04 live CD and ran Boot-Repair with recommended settings. Now Grub is completely skipped and Windows boots up. I have absolutely no idea what is going on or why I get different results every time I reinstall Grub. Here is how my partitions are set up: sda1 - Storage drive, sdb1 - Windows, sdb2 - Mac OS X, sdb3 - FreeBSD, sdb4 - Extended, sdb5 - Ubuntu, sdb6 - Shared storage, sdb7 - Shared Storage, Here's my grub.cfg file: grub.cfg

  • Why is /dev/urandom only readable by root since Ubuntu 12.04 and how can I "fix" it?

    - by Joe Hopfgartner
    I used to work with Ubuntu 10.04 templates on a lot of servers. Since changing to 12.04 I have problems that I've now isolated. The /dev/urandom device is only accessible to root. This caused SSL engines, at least in PHP, for example file_get_contents(https://... to fail. It also broke redmine. After a chmod 644 it works fine, but that doesnt stay upon reboot. So my question. why is this? I see no security risk because... i mean.. wanna steal some random data? How can I "fix" it? The servers are isolated and used by only one application, thats why I use openvz. I think about something like a runlevel script or so... but how do I do it efficiently? Maby with dpkg or apt? The same goes vor /dev/shm. in this case i totally understand why its not accessible, but I assume I can "fix" it the same way to fix /dev/urandom

  • How to find the reason for a weekly downtime on an Ubuntu web server hosted by AWS?

    - by IceSheep
    We started monitoring our web server using Pingdom and found out that we have a downtime of a few minutes every Sunday at 0:00 UTC. The test runs every minute and checks if a successful HTTP response (code 200) is returned on port 80. The test fails due to a timeout (no response after 30 seconds). Here's what we've already checked – without success: Since we run our webserver behind a load balancer, I've set the Pingdom test on the load balancer's public DNS and the webserver's public DNS in order to find out if there's a problem with the AWS load balancer – both tests return the same result We set up Munin on our webserver. Everything looked fine even after the failure. Since the last failure lasted only 2 minutes I suppose Munin couldn't capture a potential problem (it only checks every 5 minutes) I have checked /var/log/apache2/error.log and /var/log/syslog for suspicious entries I have checked /etc/cron.weekly and /etc/crontab for suspicious entries I have searched for files created or last-modified during 0:00 and 0:15 using this method: touch -t 201209020000 start touch -t 201209020015 end find / -newer start -and ! -newer end (nothing found) Has anybody experienced a similar problem? Any proposals on how to find the reason for this behavior? It's Ubuntu 10.04 LTS running on an AWS m1.large instance. Thanks!

  • Install KVM based Windows 2008 remotely over SSH on a headless, no graphics Ubuntu 10.04 server?

    - by taazaa
    Hi, I have a Dell server at a remote data center with Ubuntu 10.04 as the host. It is a minimal install with the necessary virtulization packages. There is no X and the machine is headless. I have the win2008 DVD in the machine and want to remotely install it. I tried: virt-install --connect qemu:///system -n vmwin2k8 -r 1024 --disk path=server2k8.qcow2,size=50 --cdrom /dev/sr0 --vnc --noautoconsole --os-type windows --os-variant win2k8 The qcow2 image get created However I don't understand how to connect to see the install via VNC. This is my first time doing it so it may be trivial or may not be possible. Remotely I have a Win 7 machine with Putty and RealVNC viewer. Where is the graphic output of VNC going? Do I have to have VNC server running on the host or some other machine and then connect to it from my VNC client? Please let me know or point me to the right direction. I have been searching the web for several days to figure out how this is suppose to work. Thanks!

  • Using Plesk for webhosting on Ubuntu - Security risk or reasonably safe?

    - by user66952
    Sorry for this newb-question I'm pretty clueless about Plesk, only have limited debian (without Plesk) experience. If the question is too dumb just telling me how to ask a smarter one or what kind of info I should read first to improve the question would be appreciated as well. I want to offer a program for download on my website hosted on an Ubuntu 8.04.4 VPS using Plesk 9.3.0 for web-hosting. I have limited the ssh-access to the server via key only. When setting up the webhosting with Plesk it created an FTP-login & user is that a potential security risk that could bypass the key-only access? I think Plesk itself (even without the ftp-user-account) through it's web-interface could be a risk is that correct or are my concerns exaggerated? Would you say this solution makes a difference if I'm just using it for the next two weeks and then change servers to a system where I know more about security. 3.In other words is one less likely to get hacked within the first two weeks of having a new site up and running than in week 14&15? (due to occurring in less search results in the beginning perhaps, or for whatever reason... )

  • Postgresql fails to start on Ubuntu 10.04.4 LTS

    - by cancerballs
    I installed postgresql 9.2 from add-apt-repository ppa:pitti/postgresql using apt-get install postgresql-9.2 At the end of the install and every time I try to launch postgresql by using the following command /etc/init.d/postgresql start or service postgresql start I get this error: Error: could not exec /usr/lib/postgresql/9.2/bin/pg_ctl /usr/lib/postgresql/9.2/bin/pg_ctl start -D /var/lib/postgresql/9.2/main -l /var/log/postgresql/postgresql-9.2-main.log -s -o -c config_file="/etc/postgresql/9.2/main/postgresql.conf" : [fail] invoke-rc.d: initscript postgresql, action "start" failed. dpkg: error processing postgresql-9.2 (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: postgresql-9.2 E: Sub-process /usr/bin/dpkg returned an error code (1) I have tried everything found here: How to thoroughly purge and reinstall postgresql on ubuntu and here: Eliminating non working postgresql installations on ubuntu 10-04 and starting af. I have also done dpkg -P --force-remove-reinstreq postgresql-client-9.2 in my attempt to remove everything postgres related from my server. After removing postgresql I have used dpkg --get-selections | grep postg To be sure there is nothing left and I can do a clean install. I have also made sure that the files and folders mentioned in the error message have the right permissions. The /var/log/postgresql/postgresql-9.2-main.log file is empty. I have tried installing every postgresql version from 8.3 to 9.2 and I get the same error on every time. I once managed to compile postgresql from the source provided on their website but then I encountered weird errors with psycopg2 so I figured I'd install postgresql this way and avoid those errors. Also when I type apt-get install postgresql it by default tries to install the 8.3 version even when I can find the package by typing apt-get install postgresql-9.2.

  • Ubuntu 12.04 LTS Wireless Asus USB-N53 (rt3572sta) driver installation issue

    - by Jake Thompson
    My purchase of the Asus USB-N53 just came in today and I spent several hours Googling and researching drivers for this device. When I first plugged the device in it connected fine to my open system, WEP, DHCP configured access point. I opened Google Chrome and a few pages loaded, everything seemed fine. 30 seconds later... Boom! It disconnected and showed attempts to reconnect and asked for the WEP key and just showed a state of infinite connection time until it asked me for the password again. I'm using amd64 (64 bit Ubuntu desktop 12.04 LTS) The official driver can be found here although I had no luck with it. lsusb: Bus 003 Device 002: ID 0b05:179d ASUSTek Computer, Inc. uname -a Linux Jake 3.2.0-31-generic #50-Ubuntu SMP Fri Sep 7 16:16:45 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux ----------------------------------------------------------------------------------Solved: I must of done something wrong when I originally installed the latest drivers from the chipset manufacturers website.

  • Ubuntu 13.04 running really slow and Hanging

    - by CAM
    Up till recently I have been running 13.04 on my laptop very happily. This morning however, I turned on my laptop to find it running really slow. Takes 5 min to load a program and even then the program freezes and I have had 3 system hangs this morning already. The Unity Desktop appears to run ok but programs do not. Things I have tried so far: Checking for Propitiatory graphics drivers - none shown available (I have bumblebee running already). Using the recovery boot options from Grub to repair broken packages. Recent changes - Updated computer, Installed some indicator applets which have worked fine for me before. System Specs: Asus U36s, Intel Core i5-2450M 2.5GHz, 4GB RAM, Nvidia Geforce 610M-1GB, Dual boot Win7 & Ubuntu 13.04 I'm a bit of a noob with Ubuntu but am happy enough running stuff in terminal if you will advise me on what to run. I'm just a bit stuck on what do to fix this without a reinstall. Thanks a lot for your help.

  • Ubuntu CPU Fan at 2200 RPM and CPU top at 90°C

    - by T-Erra
    I have a problem with my CPU heat. I'm running Ubuntu 14.04 (64bit) and I have issues with the cooling. I know it might be a hardware issue, but I've checked, the fan is running and in my GUI I use the command "sensors" which shows me a RPM of 2200 and a CPU temperature of 60°C while I'm not running any software. This seems to be really mysterious. However, if I start my IDE (Eclipse), Firefox and Chromium at the same time, the CPU temp goes up to 75-90° Celsius. I doubt that this is common for a system with 16 GB RAM, an i7 Processor and an Intel water cooling system and I also never had some issues like this before when I was running Ubuntu 12.04 or 13.04. Fan Speed At 60°C it's at 1300 RPM, and after start up Eclipse and Firefox it's at approximately 2200 RPM and between 75°C - 90°C depending on how many windows and IDE's I've opened. If I use the "top" command, there are just few processes like Xorg or Compiz which are taking up to 10% CPU usage at maximum, during the time I'm not running any software. I have tried to upgrade the Linux kernel, where I failed. After upgrading, I wasn't able to boot anymore so I tried to remove the new kernel from the boot directory and updated my grub file to an old entry, which works fine now, but still with the temperature issue. My NVIDIA drivers is also up to date, which dropped some issues I had before with the CPU load. So it can't be a problem with the graphic card. How can I find out, where the problem is, or why my CPU gets that high temperatures, which I only should get while playing games with high end graphics and so on? Did anyone have some similar issues before?

The problem is: files /etc/passwd and /etc/hostname and /etc/hosts where changed. /etc/passwd After John:x:1000:1000:John,,,:/home/serg:/bin/bash Befoure serg:x:1000:1000:John,,,:/home/serg:/bin/bash /etc/hosts After 127.0.0.1 localhost 127.0.1.1 John-The-Rippe Befoure 127.0.0.1 localhost 127.0.1.1 serg-Protege /etc/hostname After John-The-Ripper Befoure serg-PORTEGE-Z835 I was trying to simply changed this files but can not do this because permission denied. When I'm trying to login as a root I got this message: John@John-The-Ripper:~$ sudo -s [sudo] password for John: John is not in the sudoers file. This incident will be reported The file sudoers is empty: John@John-The-Ripper:~$ vi /etc/sudoers When I type users in cp: John@John-The-Ripper:~$ users John John When I type id, I got this: John@John-The-Ripper:~$ id uid=1000(John) gid=1000(serg) groups=1000(serg) This doesn't work eather: John@John-The-Ripper:~$ usermod -l John serg usermod: user 'serg' does not exist John@John-The-Ripper:~$ adduser serg adduser: Only root may add a user or group to the system. ater. Then I tried to go to the GRUB menu and from there log in as a root. I did this, but however When I tryed to create user serg, It gave me an error that group already exist. When I tried to change /etc/passwd it said 'permission denied' And this doens't do the trick: John@John-The-Ripper:~$ visudo visudo: /etc/sudoers: Permission denied visudo: /etc/sudoers: Permission denied Also The last thing I tried to do is to create a bootable USB and reinstall ubuntu, however I can not open USB-Creator because it asked me a root passwd. But it doesn't work. HELP ME PLEASE =)))

  • Ubuntu 12.04.1 Radeon 9550 stuck with 640x480, works in Geexbox

    - by Betty
    I am a complete new user trying to set up Ubuntu on an old desktop. It has an AGP Radeon 9550 graphics card. I am running Ubuntu from a USB drive with persistence as the PC currently has no hard drive I seem to be stuck in 640*480 mode. The desktop itself is larger, but the monitor display is stuck on 640*480. In SettingsDisplays, only the 640*480 option is available. What I have found out so far: The proprietary ati drivers no longer support my card. If 3D isn't an issue (it's not) the open source driver should be fine. This should be installed by default so in theory I am using it already xserver-xconf/pci/*.ids doesn't show any entries for the card's PCI id. hardware additional drivers show no proprietary drivers I tried the booting into the current version of Geexbox from a USB stick and this set the resolution correctly by default so I know it can be done, but I know no idea how. How can I tell what driver the card is using, and how can I get the higher resolutions back?

    We are using Physical server and are in process of Automated “ubuntu-12.04.1-server-amd64” OS installation on it. There are two HDD for OS installation purpose and there are RAID1 relation between them. This setup has been done through BIOS. The kickstart configuration file looks like this: #Generated by Kickstart Configurator #platform=AMD64 or Intel EM64T #System language lang en_US #Language modules to install langsupport en_US #System keyboard keyboard us #System mouse mouse #System timezone timezone Asia/Dili #Root password rootpw --iscrypted $1$Yl1QJyta$KzIT.kq3i9E5XaiQKcUJn/ #Initial user user ankit --fullname "Ankit" --iscrypted --password $1$c6Yflpea$pi1QQ59/jgywmGwBv25z3/ #Reboot after installation reboot #Use text mode install text #Install OS instead of upgrade install #Use Web installation url --url my_repo_location #System bootloader configuration bootloader --location=mbr #Clear the Master Boot Record zerombr yes #Partition clearing information clearpart --all --initlabel #Disk partitioning information part /boot --fstype ext4 --size 100 --ondisk sda part / --fstype ext4 --size 10000 --ondisk sda part /var --fstype ext4 --size 10000 --ondisk sda part swap --size 1024 --ondisk sdb #System authorization infomation auth --useshadow --enablemd5 #Network information network --bootproto=dhcp --device=eth0 #Firewall configuration firewall --enabled --trust=eth0 --http --ftp --ssh --telnet --smtp #X Window System configuration information xconfig --depth=8 --resolution=640x480 --defaultdesktop=GNOME But I am getting the below error : No root file system is defined Please suggest on this. Do we need to do any modification in kickstart configuration file. Any help in this regard will be very helpful for us. The automated Ubuntu OS installation is successful in Virtual Machine(VM) with the above ks.cfg (kickstart configuration file ) but failing in case of physical machine. Please suggest on this and if possible provide the new ks.cfg file to resolve above problem. Thanks & Regards, Rajesh Prasad

  • Ubuntu 14.04 boot error on Windows 8.1 - SYSLINUX 4.07 EDD

    - by nainai
    I want to replace Windows 8.1 that came with my laptop with Ubuntu 14.04. I keep getting a black screen with this line: SYSLINUX 4.07 EDD 2013-07-25 Copyright (C) 1994-2013 H. Peter Anvin et al Things I did before: turned off fast boot disabled secure boot switched to Legacy instead of UEFI (even though a tutorial I found said this isn't really needed anymore, I still did anyway because I read it from the laptop's user guide: "If you need to install a legacy operating system, such as Windows (that is, any operating system before Windows 8), Linux or Dos, etc on your computer, you must change the boot mode to Legacy support." I chose to load from USB. and then that SYSLINUX 4.77 EDD.... appears I tried to install using the same USB on an old Lenovo S10-3. It worked. Though that S10-3 runs Lubuntu. Still it's probably safe to say that it's not the USB that has problems, right? Thanks for any help. I can't wait to have Ubuntu :) edit: This might be useful info. The USB is 16GB X-Stor Fat32. I used YUMI.

  • Ubuntu can't find the correct max resolution with Samsung SyncMaster SA300

    - by fatmatto
    i decided to install ubuntu also on my desktop PC (Windows has been exorcised from my life) but i am having some problems i didn't have with previous hardware configurations. My display is a Samsung SyncMaster SA300, on windows vista the maximum resolution (1920x1080) worked well, but now, ubuntu (after installing fglrx drivers) tells me that the maximum resolution is 1600x1200 I googled a lot last night, and i found a lot of people solving this (on different displays though) with xrandr. I was not able to do it, because xrandr keep complaining "you goddamn maximum resolution is 1600x1600". What xranrd clean command say is: mattia@fatdesktop:~$ xrandr Screen 0: minimum 320 x 200, current 1600 x 1200, maximum 1600 x 1600 DFP1 disconnected (normal left inverted right x axis y axis) CRT1 disconnected (normal left inverted right x axis y axis) CRT2 connected 1600x1200+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1600x1200 60.0*+ 1400x1050 60.0 1280x1024 60.0 47.0 43.0 1440x900 59.9 1280x960 60.0 1280x800 60.0 1152x864 60.0 47.0 43.0 1280x768 59.9 56.0 1280x720 60.0 50.0 1024x768 60.0 43.5 800x600 60.3 56.2 47.0 720x576 50.0 720x480 60.0 640x480 60.0 TV disconnected (normal left inverted right x axis y axis) CV disconnected (normal left inverted right x axis y axis) Then according to other internet posts and forums: mattia@fatdesktop:~$ cvt 1920 1080 60 # 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync So now i have to add that modeline mattia@fatdesktop:~$ xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync mattia@fatdesktop:~$ xrandr --addmode CRT2 1920x1080_60.00 And here comes the pain: mattia@fatdesktop:~$ xrandr --output CRT2 --mode 1920x1080_60.00 xrandr: **screen cannot be larger than 1600x1600 (desired size 1920x1080)** See? screen cannot be larger than 1600x1600 (desired size 1920x1080) At this point, the 1920x1080 option appears inside the resolution choice menu (the graphical one). But last night, when i tried to select it, my screen went black, and i had to power off the pc. Any clues? am i on the wrong path?

  • Nautilus crashes after Ubuntu Tweak Package Cleaner [fixed]

    - by Ka7anax
    Few days ago I started having some problems with nautilus. Basically when I'm trying to get into a folder it crashes. It's not happening all the time, but in 85% it does... Sometimes, after the crash all my desktop icons are also gone. The only thing that I think causes this is Ubuntu Tweak - I'm not sure, but the issues started after I did the Package cleaner from Ubuntu Tweaks... Any ideas? ------- EDIT 2 - IMPORTANT !!! ---------- It seems I fixed this problem doing these: 1) I uninstall this nautilus script - http://mundogeek.net/nautilus-scripts/#nautilus-send-gmail 2) I installed nautilus elementary So far is back to normal... If anything bad happens again I will come back! -------- EDIT 1 ---------- First time, after running the command (nautilus --quit; nautilus --no-desktop) 3 times all the system crashed (except the mouse, I could move the mouse). After restart I run it and obtain this: ----- Initializing nautilus-gdu extension Initializing nautilus-dropbox 0.6.7 (nautilus:2966): GConf-CRITICAL **: gconf_value_free: assertion value != NULL' failed (nautilus:2966): GConf-CRITICAL **: gconf_value_free: assertionvalue != NULL' failed Nautilus-Share-Message: Called "net usershare info" but it failed: 'net usershare' returned error 255: net usershare: cannot open usershare directory /var/lib/samba/usershares. Error No such file or directory Please ask your system administrator to enable user sharing. and then this: cristi@cris-laptop:~$ nautilus --quit; nautilus --no-desktop (nautilus:3810): Unique-DBus-WARNING **: Error while sending message: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
