  • issues with ASUS S301L ultrabooks

    - by Wuerze
    I just like to tell you what still is a Problem in Ubuntu 14.04 and should be solved for a nice experience of this distribution. Unfortunately I do not have any hints to tell you, because I am just a user and know not much about programming. Anyway, I hope it helps. 1) Intel open source Graphics issues (proprietary) -when attaching HDMI-cable the screen switches to the external monitor and it's fine, but there is no switching back unless restart with HDMI deattached -black screen appears for like 2 seconds as if I would change screen in the settings; frequency increases with intensity of driver use (i.e. videos or video games) 2) hotkeys (commonly recognised) -there is no possibility to adjust brightness with the hotkeys (Fn+F5 and Fn+F6) 3) touchscreen (commonly recognised) -the touchscreen is behaving like a mouse -configuring gestures for the multi touch screen seems to always end in disabling touch pad gestures 4) panel symbols -battery symbol has got a low accuracy while it determines accurately the energy left; only 5 steps of energy are shown by the symbol Thank you all for participating in the solution of these problems! I will stay tuned and edit this list if something has been solved.

  • Upgrading Windows 7 on a new Netbook - Problems

    - by Swaffle
    I know this seems like a repeat of a question but i didn't get a clear answer from reading the other questions so im going to ask mine and hope i hear back good news. I bought an Acer Aspire one netbook with windows 7 starter. I have a DVD of Windows 7 Professional(x86) from MSNDAA through my college but when i tried to install it, i was given an error saying that i could only upgrade through the "Windows Anytime Upgrade" Though, it only gives me the options of paying for an upgrade, which im not willing to do, or putting in an upgrade key. I have a legitimate product key for windows 7 but it does not work for upgrading and the DVD does not allow for it. Am i doing something wrong? is there another option? can i convert my product key to an upgrade key ? Im up for any option, windows 7 starter is pretty limited in its features...

  • Apple Wireless (aluminium) Keyboard on Windows

    - by Dave Arkell
    I have an apple wireless keyboard which I am using with my windows pc and it works excellently, and looks superb. It all connects fine (particularly with a flashed dbt-120). However, I haven't had great success with getting all those useful keys to work with the 'fn' key. I've been using uawks as a way to get it working, but it doesn't always work. Has anyone had success with any other tools to get the fn key working (and therefore creating shortcuts to 'End', 'Home', 'Break', 'Pgup', etc? I should point out that this is not a mac computer, it is a plain old pc.

  • How to add a font to the Cmd window choices in Windows 7 64-bit?

    - by Mark Ransom
    I tried following the procedure outlined in this previous answer and it doesn't work: http://superuser.com/a/5079/2366 Specifically I'm trying to add Lucida Sans Typewriter Regular to the choices of Consolas and Lucida Console that the Cmd window currently allows. Lucida Console is in registry key "0" and Consolas is in registry key "00", so I'm adding key "000" but it's not affecting the available choices in the Font tab under Properties, even after rebooting the system. P.S. I also tried adding Courier New to the choices and it shows up, but appears to select Italic instead.

  • 2 folders in Sys/Class/Backlight?

    - by zebrapie
    ISSUE: Backlight brightness does not change. More Detail: Brightness will not change, using both 'System Settings-Screen', or FN keys (Brightness bar shows and moves, but screen brightness does not change). Notcied a post in this thread (http://ubuntuforums.org/showthread.php?t=1866283) about having multiple folders in Sys-Class-Backlight... I HAVE TWO FOLDERS TOO! 'intel_backlight' and 'acpi_video0' Using the function keys, alters the value in the acpi_video0's 'Brightness' file - But doesn't actually alter the brightness of the screen. If I add 'backlight=vendor' in Grub, my function keys then edit the value in the 'Intel_Backlight brightness file. - But again doesnt actually change the brightness of the screen. Computer: Fujitsu Siemans Pi2515, Intel Integrated Graphics, No hdd partition. Already Tried: -Editing grub to contain: acpi_osi=Linux acpi_backlight=vendor -http://ubuntuguide.net/change-screen-brightness-with-fn-key-in-ubuntu-11-0410-10 -sudo apt-get install acpi -$ sudo setpci -s 00:02.0 F4.B=20 -Brightness does not adjust in fallback mode either. -Reinstalling OS, Using Linux Mint (Same problem). -Upgrading and downgrading BIOS. Many thanks for reading, I understand this problem may need a bit of a Linux pro to sort. If anyones up for the challenge i'll spend any amount of time being walked through this, posting results. Don't want to give up here!

  • Laptop power button not working

    - by DyP
    I have a (seemingly rather exotic) Dell Latitude XT2 notebook running Lubuntu 12.04, fresh install. Tried to get the power button to work as expected (opening lubuntu-logout, just as I think it was meant to be out-of-the box), but no success: power button does nothing but forced power-off on long press. Here some more information, please ask if something more could help: Power button is recognized as a device: xinput lists Power Button as a slave keyboard at /dev/input/event1, and I can run a tool to listen to that device and invoke some action (successfully). But using .config/openbox/lubuntu-rc.xml to assign some action to XF86ShutDown or XF86PowerOff does nothing. Works well for any key of the keyboard. xinput --test reports a keycode (key press, key release) of 124 when pressing & releasing the power button. xmodmap -pk lists 124 mapped to XF86PowerOff which seems correct to me (btw: is this the same as XF86ShutDown?) When assigning another keysymname to the 124 keycode, e.g. 'w', still nothing happens when pressing the power button (no window seems to receive a 'w'). Works well for any key on the keyboard. The outputs of xev for a press/release of the power button irritate me: MappingNotify event, serial 41, synthetic NO, window 0x0, request MappingKeyboard, first_keycode 8, count 248 FocusOut event, serial 41, synthetic NO, window 0x2a00001, mode NotifyGrab, detail NotifyAncestor FocusIn event, serial 41, synthetic NO, window 0x2a00001, mode NotifyUngrab, detail NotifyAncestor KeymapNotify event, serial 41, synthetic NO, window 0x0, keys: 93 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 (instead of 93, I also get different values) I might have missed something very basic since I'm not very familiar with both openbox/lubuntu and the X input system. Btw.: same goes for three other special buttons on my laptop..

  • Windows 7 is swallowing a keystroke combination

    - by Mike K
    I'm using the gnu emacs editor under windows 7. I would like to bind a particular keystroke combination to an editor command. That combination is "control key" + ")", i.e., "control key" + "shift key" + "0". However, it appears this keystroke combination is being swallowed by the OS somehow. Using emacs's "view-lossage" feature indicates that it is never seeing the key. This happens even in safe mode. It does not happen under windows XP. Anyone know of a way to fix / diagnose what's happening?

  • OpenVPN - Cannot browse ipv4 websites

  • Why specifying keyboard layout?

    - by amyassin
    Most operating systems (if not all) asks about the keyboard layout during installation. Why do they need to know the layout? I mean, when pressing key, does the keyboard send a specific signal indicating what it represents (if so, why needing to specify the layout?) or it sends a signal indicating its position (the second raw, third key) and then the OS detects what key is that from the layout specified?

  • Synergy: Is there a way to push Win+L to all screens, not just the server?

    - by Offbeatmammal
    When I hit Win+L on either of my machines I'd ideally like to be able to lock both client and server What happens though is no matter which screen I hit the key combination... it locks the server. I'm guessing the OS is trapping the key sequence before it can get passed to the app to manage, so I'm happy to use a different key sequence as long as the result will be the same Synergy 1.4.2 64 bit Beta

  • Change MacOS X guest screen resolution for VirtualBox

    - by Pymoo
    I have tried all alternatives and resources that I found on internet to achieve to change screen resolution in my MacOS X guest. I have the latest VirtualBox version (4.1.22) and I have MacOS X 10.6.3 Snow Leopard running in a vm guest. Some solutions that don't work for me are: Tuning virtual machine settings: Adding and in the .vbox file, or running these two commands: vboxmanage setextradata "MAC OS X" "CustomVideoMode1" "1360x768x32" vboxmanage setextradata "MAC OS X" "GUI/CustomVideoMode1" "1360x768x32" Editing Guest OS boot configuration: Modify /Library/Preferences/SystemConfiguration/com.apple.boot.plist with these lines: <key>Kernel Flags</key> <string>"Graphics Mode"="1360x768x32"</string> <key>Graphics Mode</key> <string>1360x768x32</string> Any other suggestion, something that I was missing.

  • Linux will not activate wireless after device has been re-enabled

    - by XHR
    Using a Eee 900A netbook by Asus. By pressing Fn + F2, I can disable or enable the wireless chip on the netbook, a blue LED indicates the status. I've been able to connect to wireless networks just fine with this netbook. However, if the wireless chip ever becomes disabled, I have to reboot to get my network connection back. This generally happens when suspending. For some reason the LED will be off and I have to hit Fn + F2 for it to light up again. However, after doing so, Linux will not reconnect to the network. It simply changes the wireless status from "wireless is disabled" to "device not ready". Even worse, I've recently had issues with the chip being enabled at boot, thus making it nearly impossible to get connected. I've searched around on-line but haven't found much of anything useful on this. This happens on all kinds of different distros including Ubuntu 9.10 Netbook, EeeBuntu 4 beta, Jolicloud and Ubuntu 10.04 Netbook.

  • How to deal with ssh's "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!"?

    - by Vi.
    I often need to login to multiple remote stations that are just placed to the same static IPs for me. SSH complains about changed keys in this case: $ ssh [email protected] @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ ... Offending RSA key in /home/vi/.ssh/known_hosts:70 ... I usually just run vim /home/vi/.ssh/known_hosts +70, dd wq and re-run the SSH command. How to do it simpler? Requirements: The warning should be displayed, and not like this: The authenticity of host '172.1.2.3 (172.1.2.3)' can't be established. It is easy to accept the key change. I expect something like this: $ ssh [email protected] @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ ... The fingerprint for the RSA key sent by the remote host is 82:cd:be:7a:ae:1b:91:2c:23:c1:74:4d:8a:38:10:32. Change the host key in /home/vi/.ssh/known_hosts (yes/no)? yes Warning: Changed host key for '172.1.2.3' (RSA) in the list of known hosts. [email protected]'s password: Simple and differs from usual "The authenticity of host can't be established." message.

  • Run command automatically as root after login

    - by J V
    I'm using evrouter to simulate keypresses from my mouses extra buttons. It works great but I need to run the command with sudo to make it work so I can't just use my DE to handle autostart. I considered init.d but from what I've heard this only works for different stages of boot, and I need this to run as root after login. $ cat .evrouterrc "Logitech G500" "/dev/input/event4" any key/277 "XKey/0" "Logitech G500" "/dev/input/event4" any key/280 "XKey/9" "Logitech G500" "/dev/input/event4" any key/281 "XKey/8" $ sudo evrouter /dev/input/event4

  • If I drop my clustered PK and add a new one, what order will my rows be in?

    - by stack
    In SQL Server, I'm looking at TableA, which currently has a uniqueidentifier clustered primary key. The GUID has no meaning in any context. (I'll give you a second to clean up your keyboard and monitor and set down the soda.) I'd like to drop that primary key and add a new unique integer primary key to the table. My question is this: when I drop the index, modify the column from uniqueidentifier to int, and add the new clustered unique primary key to the modified column, will the new PK values be in the order of insertion into the table, or will they be in some other order? Is this the right way to go here? Will this work? (I'm kind of a noobkin with regard to table creation/modification.)

  • Accessing or Resetting Permissions of a Mounted Registry Hive of a Different User / From a Different System

    - by Synetech
    I’m currently stuck using my backup system until I can replace my dead motherboard. In the meantime, I have put my hard-drive in this system so that I can access my files and keep working on the backup system. Fortunately, I don’t have a permission issues with the files (the partitions are FAT32). The issue I’m having is with the registry. I need to import some of my settings from the hives of my (old? normal?) installation of Windows into the one I’m currently using. Settings from the system hives (SYSTEM, SOFTWARE, etc.) are fine, but the user hive is giving me trouble. I’ve copied the NTUSER.DAT file from my other drive and mounted it with the reg command. Most of the keys (eg Software) are fine and I can access them without problem, but some of them (particularly the Identities key where Outlook Express settings are stored) complains that it cannot be opened. If I open the permissions dialog, I get an error about being unable to view the current permssions. If I then ignore it and try to take ownership of the key and it’s subkeys, I get an access-denied error. If I then add permissions for my user account on this system, I get an error, however I am then able to see the subkeys and values of the key. If I then try to access the subkeys, I get the same original errors. If I repeat the process for each subkey, I can see their values and subkeys, and so on, but of course this gets to be incredibly annoying and time-consuming (especially since the Identities key has a lot of subkeys). Is there an easier/temporary/more correct way to dump a key so that I can import it into my backup system?

  • Why isn't passwordless ssh working?

    - by Nelson
    I have two Ubuntu Server machines sitting at home. One is 192.168.1.15 (we'll call this 15), and the other is 192.168.1.25 (we'll call this 25). For some reason, when I want to setup passwordless login from 15 to 25, it works like a champ. When I repeat the steps on 25, so that 25 can login without a password on 15, no dice. I have checked both sshd_config files. Both have: RSAAuthentication yes PubkeyAuthentication yes I have checked permissions on both servers: drwx------ 2 bion2 bion2 4096 Dec 4 12:51 .ssh -rw------- 1 bion2 bion2 398 Dec 4 13:10 authorized_keys On 25. drwx------ 2 shimdidly shimdidly 4096 Dec 4 19:15 .ssh -rw------- 1 shimdidly shimdidly 1018 Dec 4 18:54 authorized_keys On 15. I just don't understand when things would work one way and not the other. I know it's probably something obvious just staring me in the face, but for the life of me, I can't figure out what is going on. Here's what ssh -v says when I try to ssh from 25 to 15: ssh -v -p 51337 192.168.1.15 OpenSSH_5.9p1 Debian-5ubuntu1, OpenSSL 1.0.1 14 Mar 2012 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug1: Connecting to 192.168.1.15 [192.168.1.15] port 51337. debug1: Connection established. debug1: identity file /home/shimdidly/.ssh/id_rsa type 1 debug1: Checking blacklist file /usr/share/ssh/blacklist.RSA-2048 debug1: Checking blacklist file /etc/ssh/blacklist.RSA-2048 debug1: identity file /home/shimdidly/.ssh/id_rsa-cert type -1 debug1: identity file /home/shimdidly/.ssh/id_dsa type 2 debug1: Checking blacklist file /usr/share/ssh/blacklist.DSA-1024 debug1: Checking blacklist file /etc/ssh/blacklist.DSA-1024 debug1: identity file /home/shimdidly/.ssh/id_dsa-cert type -1 debug1: identity file /home/shimdidly/.ssh/id_ecdsa type -1 debug1: identity file /home/shimdidly/.ssh/id_ecdsa-cert type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.9p1 Debian-5ubuntu1 debug1: match: OpenSSH_5.9p1 Debian-5ubuntu1 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.9p1 Debian-5ubuntu1 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: sending SSH2_MSG_KEX_ECDH_INIT debug1: expecting SSH2_MSG_KEX_ECDH_REPLY debug1: Server host key: ECDSA 54:5c:60:80:74:ab:ab:31:36:a1:d3:9b:db:31:2a:ee debug1: Host '[192.168.1.15]:51337' is known and matches the ECDSA host key. debug1: Found key in /home/shimdidly/.ssh/known_hosts:2 debug1: ssh_ecdsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: Roaming not allowed by server debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,password debug1: Next authentication method: publickey debug1: Offering RSA public key: /home/shimdidly/.ssh/id_rsa debug1: Authentications that can continue: publickey,password debug1: Offering DSA public key: /home/shimdidly/.ssh/id_dsa debug1: Authentications that can continue: publickey,password debug1: Trying private key: /home/shimdidly/.ssh/id_ecdsa debug1: Next authentication method: password

  • Missing Driver - Video Controller (VGA Compatible)

    - by arahant
    I have a HP 2000-2106TU Notebook PC running Windows XP. I want to get the brightness keys to work. They are placed over the F2 and F3 buttons and are meant to be used in conjunction with the Fn key. But these combinations do not work, though other Fn keys such as the volume control keys do. I see a missing driver for a device called Video Controller (VGA Compatible) in the Windows Device Manager. The hardware id is PCI VEN 8086 DEV 0106 SUBSYS_1858103C which a Google search suggests is in an Intel HD Graphics family, but I don't know where to locate the driver. HP's driver scan does not help, as it does not show any missing driver related to video/graphics. What can I do next?

  • Can't connect to Wireless

    - by SimplyRed37
    Good day all! I hope you are doing good. I have performed a WUBI installation of 12.04 on my HP G62 laptop, which has an Atheros AR9285 wireless chipset. Everything works fine with my wired network connection. However, wireless is unable to connect to my wifi network. I enter the WPA2 key and then it attemps to connect, but eventually comes back, asking for the WPA2 key again, as if it was not good. All of the other laptops in the household are able to connect, using the same key (I configured them all, so I am 500% sure of the WPA2 key). Any idea as to what could be causing this? I can definitely post the output of CLI commands like "rfkill list" or "sudo lshw -class network", or "ifconfig". I have installed Ubuntu a few time but I am definitely still a newbie, but I am definitely computer savyy. Looking forward to suggestions . Thanks in advance !!! Dan...

  • Mysql: Working With 192 Trillion Records... (Yes, 192 Trillion)

    - by Sarah
    Here's the question... Considering 192 trillion records, what should my considerations be? My main concern is speed. Here's the table... CREATE TABLE `ref` ( `id` INTEGER(13) AUTO_INCREMENT DEFAULT NOT NULL, `rel_id` INTEGER(13) NOT NULL, `p1` INTEGER(13) NOT NULL, `p2` INTEGER(13) DEFAULT NULL, `p3` INTEGER(13) DEFAULT NULL, `s` INTEGER(13) NOT NULL, `p4` INTEGER(13) DEFAULT NULL, `p5` INTEGER(13) DEFAULT NULL, `p6` INTEGER(13) DEFAULT NULL, PRIMARY KEY (`id`), KEY (`s`), KEY (`rel_id`), KEY (`p3`), KEY (`p4`) ); Here's the queries... SELECT id, s FROM ref WHERE red_id="$rel_id" AND p3="$p3" AND p4="$p4" SELECT rel_id, p1, p2, p3, p4, p5, p6 FROM ref WHERE id="$id" INSERT INTO rel (rel_id, p1, p2, p3, s, p4, p5, p6) VALUES ("$rel_id", "$p1", "$p2", "$p3", "$s", "$p4", "$p5", "$p6") Here's some notes... The SELECT's will be done much more frequently than the INSERT. However, occasionally I want to add a few hundred records at a time. Load-wise, there will be nothing for hours then maybe a few thousand queries all at once. Don't think I can normalize any more (need the p values in a combination) The database as a whole is very relational. This will be the largest table by far (next largest is about 900k) UPDATE (08/11/2010) Interestingly, I've been given a second option... Instead of 192 trillion I could store 2.6*10^16 (15 zeros, meaning 26 Quadrillion)... But in this second option I would only need to store one bigint(18) as the index in a table. That's it - just the one column. So I would just be checking for the existence of a value. Occasionally adding records, never deleting them. So that makes me think there must be a better solution then mysql for simply storing numbers... Given this second option, should I take it or stick with the first... [edit] Just got news of some testing that's been done - 100 million rows with this setup returns the query in 0.0004 seconds [/edit]
