  • Can I use HDMI with the Intel card of my optimus laptop?

    - by Byakkun
    I have an Dell Inspiron 7110 that has a Sandy bridge i7 and a discrete graphics card (GeForce 525M) from Nvidia. I want to be able to use my 23' display at home throungh hdmi but Intel integrated graphics card does not work with hdmi (VGA is not an option). I have tried bumblebee but it does not work. How could I use the hdmi port for my monitor. Using only the nvidia card with some driver is what I tought i could do but i don't want to give up composing because I use gnome-shell. Any options for doing this?

  • Creating basic ACPI event makes the system unusably slow

    - by skerit
    I want to change a few settings on my laptop when I switch to battery power. I created a new event in /etc/acpi/events/cust-battery and it looks like this: event=battery action=/home/skerit/power.sh I put a simple command in the power.sh file: echo This is a test >> /home/skerit/powertest Now, when I tail this file it shows "This is a test" 4-5 times upon switching to battery power. However, the system becomes totally unstable. It slows down significantly. I can't change anything in the terminal. The terminal and certain parts of the screen (like the gnome system monitor applet) go blank from time to time. What can be the cause of that? It's a simple echo that gets executed a few times!

  • How do I disable/modify CPU underclocking due to temperature on a laptop with a 2nd generation core cpu?

    - by Tyson Marchuk
    I am running Ubuntu 11.04 on a tablet with a Core i5-2557M processor. When doing processing intensive tasks the CPU is forcibly under-clocked to 800MHz (instead of the normal base of 1.7GHz.) The CPU temperature is around 75 C. I have disabled CPU scaling (set governor to performance) but this seems to have no effect. I would like to either modify the behavior so that the throttling happens at 95 C or I would like to disable it altogether. Changing the min/max frequency as root using cpufreq works until the temperature rises and then it ceases to work, ignoring a minimum frequency above the 800MHz. On Windows 7 there is a 3rd party utility that can do this (ThrottleStop). Thank you.

  • How to set Laptop Brightness in Gnome and /proc on Thinkpad W510?

    - by hakre
    I can set the brightness of my laptop screen already via /proc. I can read and change the value. Now I've set the value to 33 and then I went into gnome power management and enabled the option that it should reduce the backlight brightness being on battery. That works, the screen gets darker. If I now read out the current setting from /proc it still says it's 33. So I assume that there is another node in /proc to be used to control the brightness. The node I use so far is: /proc/acpi/video/VID/LCD0/brightness I'm using the nouveau driver. With the nvida driver the brightness can not be controlled.

  • Can I set up two computers up with the same monitors/keyboard/mouse in a modular way?

    - by CodeJunkie
    I have a desktop computer computer (running Windows 7), and a laptop (running OSX Mountain Lion, and maybe Ubuntu 12 eventually). When the laptop is at home, I want both the desktop and the laptop to use the same (2+) monitors, the keyboard, and the mouse (or mice, if I add a track pad). I know about KVM switches, but I want something more complicated. I like to use Synergy to use both computers with one keyboard and mouse at the same time. Synergy requires that the keyboard and mouse be connected to one computer (the server), which shares them with other computers (clients) over wifi. the issue is that when one computer isn't logged in, Synergy doesn't work on it. Sometimes, I want my laptop to be the server (physically connected to the keyboard and mouse), and sometimes I want my desktop to be the server. This means that I need the keyboard/mouse/other USB devices to be able to switch computers without me playing musical plugs. To complicate things further, I don't always want the same desktop set up in terms of monitors. Sometimes, I want the desktop to have both monitors. Other times, I want the laptop to control both monitors. Sometimes I want the desktop to control one monitor, and the laptop to control the other. In any case, the keyboard and mouse need to be able to be physically connected to either computer without lots of fussing with plugs. This breaks down to at least this set of possible combinations: Desktop controls both monitors, and has a physical connection to keyboard and mouse Laptop controls both monitors, and has a physical connection to keyboard and mouse Desktop and laptop each control a monitor, but the desktop has a physical connection to the keyboard and mouse (which it shares with the laptop via wifi) Desktop and laptop each control a monitor, but the laptop has a physical connection to the keyboard an mouse (which it shares with the desktop via wifi) some usb devices connected via a usb hub need to be able to switch physical connection between computers, ideally without the keyboard and mouse switching computer connection There may be other combinations, but these are the main ones at the moment. Basically, I need a KVM switch which allows me to switch individual monitors/keyboard/mouse/usb hub between computers independently of each other, or a better solution. How can I set two computers up with the same monitors/mice/keyboard/usb hub without having to switch everything to one computer or the other all at the same time?

  • Restart mysql keeping the data

    - by sitonico
    I'm quite new using mysql, so let me know if I'm missing something. I took some holidays, and when I got back to work and I tried to log in phpmyadmin I got a ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2). I never had this problem, so I was browsing to look for a solution. I tried some things, and I'm afraid I touched too much. I couldn't solve the problem, and the I realized that I had some actualizations to be done, and I thought that they may be helpful for mysql. Then I also realized that when I was doing this actualizations first day, they stopped because I had a lack of space, so I restarted then. Then,when the system was configuring mysql, it didn't advance. I waited for a long time and then I just stopped it and restarted the computer. After it, I just tried to uninstall mysql with sudo apt-get remove mysql-server-5.1, and install it again, but it didn't work. Now I have 2 questions: What do you think it is happening? Should I remove mysql completely? What should I do? I'm afraid of losing my databases, is there anyway to recover the data? Thank you very much in advance. -----------EDIT------- These are the messages: alfonso@alfonso-laptop:/$ tail -F /var/log/syslog | grep Feb 15 15:08:01 alfonso-laptop init: mysql post-start process (15192) terminated with status Feb 15 15:08:01 alfonso-laptop init: mysql main process (15263) terminated with status Feb 15 15:08:01 alfonso-laptop init: mysql main process ended, Feb 15 15:08:31 alfonso-laptop init: mysql post-start process (15264) terminated with status Feb 15 15:08:31 alfonso-laptop init: mysql main process (15358) terminated with status Feb 15 15:08:31 alfonso-laptop init: mysql main process ended, Feb 15 15:09:01 alfonso-laptop init: mysql post-start process (15359) terminated with status Feb 15 15:09:01 alfonso-laptop init: mysql main process (15447) terminated with status Feb 15 15:09:01 alfonso-laptop init: mysql main process ended, Feb 15 15:09:32 alfonso-laptop init: mysql post-start process (15448) terminated with status 1 This is the content of error.log-old 110128 13:17:20 [Note] /usr/sbin/mysqld: Normal shutdown 110128 13:17:20 [Note] Event Scheduler: Purging the queue. 0 events 110128 13:17:20 InnoDB: Starting shutdown... 110128 13:17:22 InnoDB: Shutdown completed; log sequence number 0 590872 110128 13:17:22 [Note] /usr/sbin/mysqld: Shutdown complete 110214 2:08:18 [Note] Plugin 'FEDERATED' is disabled. 110214 2:08:19 InnoDB: Started; log sequence number 0 590872 110214 2:08:19 [Note] Event Scheduler: Loaded 0 events 110214 2:08:19 [Note] /usr/sbin/mysqld: ready for connections.

  • How can I disable the IR/Remote Control on an HP Laptop?

    - by Steve Rowe
    I've seen this happen on 2 different HP laptops now. If I try to use them in the same room as a Media Center, the MCE TV remote keeps sending commands to the laptop. This can do anything from wake it up and turn it on to just moving the selection around. There is no obvious way to disable the IR sensor or at least its response to the remote. Does anyone know how to do this?

  • How do I disable a laptop's build-in keyboard on ubuntu?

    - by David
    I have a Kinesis keyboard that I ideally like to use by placing it on top of my laptop. When I do that, I wind up pressing keys on the built-in keyboard with my external keyboard. I've been playing around with the GUI keyboard controls and reading the ubuntu forums for a couple hours without really any forward progress. Even a hacky solution or a pointer to a good library for configuring multiple keyboards differently would be much appreciated. thanks.

  • SQL Server 2005 on laptop. Not sure if I can delete

    - by WebDevHobo
    I have SQL Server 2005 on this laptop. I probably got installed along with Visual Studio. The thing is, I don't use it and it's constantly running. Process Explorer reports that it has a virtual Size of 1.5 GB. I want to uninstall this, but I'm not sure if there are any other processes dependent on this.

  • Is it safe to have NVidia graphics always on on a Linux laptop, or do I risk overheating?

    - by codeape
    I'm getting a Lenovo T520 with two graphics cards: Integrated Intel HD 3000 Discrete NVidia NVS 4200M In BIOS, I can adjust which card(s) to use: Integrated only Discrete only Both (NVidia optimus) Since optimus is not well supported under Linux, I wonder if it is OK to set up the system to use the NVidia card all the time. I have read somewhere that a laptop risks overheating if using a discrete graphics card all the time. Is this true? Does someone have any experience to share?

  • Is auto-logon on laptop with encrypted hard drive secure?

    - by Tobias Diez
    I have the complete hdd of my laptop encrypted (with the Windows built-in Bitlocker) and thus have to login two times upon booting (Bitlocker and user account). Since I'm the only person using the computer (and knowing the Bitlocker password), I was thinking about automatically login into the user account to make the boot process smoother and quicker. In which cases/scenarios is this a bad idea and the additional login gives a true additionally layer of security?

  • What is the function of those film covers on electronic equipment such as mobile screens but also peripheral plastics on a laptop?

    - by leladax
    I understand it may "protect" an area but I don't get why the customer gets it and then takes it off after it was being protected in a full box anyway. Also, should those film covers that surround the plastics around a laptop screen (and not the screen itself) and maybe also on the keyboard be kept on as much as possible? I noticed if one tries to keep them on as much as possible they tend to go off by themselves anyway, but anyway, what's the status quo about it?
