General :: Screen Not Showing On Laptop But Showing On Projector When Connected

Apr 18, 2011

When I try to connect a projector to my laptop (already running) and hit the fn+f7 (the designated button for switching screen), nothing happens. I see "no source found" on projector screen and my laptop screen works perfectly. Now if I restart the laptop with the projector connected, I see all the intial booting messages on the projector screen (not on my laptop), then the gnome login screen appears on both the projector screen and laptop (when the login screen appears on laptop it looks like it has lower resolution than my usual laptop resolution). But immediately after I log in, my laptop screen goes blank, and projector screen becomes the only active screen.

If I restart without the projector, again all normal operation on laptop screen is restored.

I feel like I am missing some very silly options. Any help is appreciated.

Here is the output of xrandr when the laptop is connected:

Debian Configuration :: Connected To Internet Yet Server Not Found?

Sep 20, 2010

I just reinstalled debian on my computer, I've had it working for a long time, only difference is I used to have Cable Internet and now I use DSL. Anywho, I reinstalled debian from the kde CD on the debian website, it auto-configured my network out of the box. My network is connected to the computer, pinging google works perfectly, and ifconfig shows that eth0 is working correctly without any errors. However on both Konqueror and Iceweasel, every time I try to connect to a website, it tells me the server cannot be found. Basically it acts like I don't have internet. Using the terminal works though, I have installed KDE-FULL from the terminal and wicd, so I know I do have internet. I don't know what it could be, like I said, I installed from the cd and this happened. Maybe there's a bug on the KDE debian cd

Debian Configuration :: Network Manager Says No Internet Is Connected

May 16, 2011

I just installed, and evolution doesn't seem to think it has internet. The icon with the power cord in the bottom left is unplugged, and send/receive is greyed out. Internet is working , but it is not using network manager, since network manager says no internet is connected. Maybe this has something to do with it?

Debian Configuration :: Network-manager & Auto Scanning While Connected

May 6, 2010

I'm trying to use network-manager in sid and it's incredibly frustrating because every 2 minutes or so it seems to scan for wireless access points, during which time my SSH connections completely hang and screw up. Pings start dropping packets as well. By doing an "iwlist scan" I can reproduce the behavior. Has anyone else dealt with this? I haven't been using network-manager, but I am currently due to mobility and needed VPN functionality... WICD with no network-manager works better but there's no gui-based VPN support. I've got an Atheros wireless device and I've read that supposedly it should be doing background scanning since kernel 2.6.32, but I haven't seen anything like that, and I'm on 2.6.32-5-amd64 currently, 2.6.32-3-amd64 behaves the same too.

Debian Configuration :: Networking: Connected To Wifi, Webpages Won't Resolve?

Oct 2, 2010

I just installed Debian with the latest testing iso, and I'm having problems connecting to the web via browser. I can ping hostnames (i.e.,, etc.) from the terminal and it resolves just fine, but if I try to load a page from Iceweasel or Epiphany it says the page won't load because it can't resolve the hostname. Can someone tell me what I'm missing?the detail that I'm running amd64. I've checked iptables and found no entries, and for good measure I flushed it to be certain. I also checked resolv.conf but that looked normal, just a nameserver entry pointing to my home router. I'm new to Debian, but have used Linux for years, and I'm genuinely stumped. I'm sure the solution will smack me in the head for its simplicity, but nonetheless I need at least a shove in the right direction.

Debian Configuration :: Usage Of SMTP With Temporarily Connected Network?

Jun 15, 2011

I'm currently running my own postfix server which is the MX for my domain. This is hosted in my house at the moment on the end of an ADSL line with a static IP. However, I'm trying to go totally mobile so I can kill the ADSL and the line rental and switch to 3G. Does anyone know a solution which allows me to accept (or ask for delivery) of SMTP when temporarily connected and queues it externally? Sort of like a hosted mail queue which pumps SMTP onto my laptop only when I ask it to.

Debian Configuration :: Bluez Gatt Tool Not Connected To Hcix Device

Apr 19, 2016

Using jessie over 4.2.8 or 4.3.4 kernel.

Used both the default bluez package, 5.23 and building bluez 5.36 by hand.

hciconfig shows a good configuration,

hci0: Type: BR/EDR Bus: UART
BD Address: 78:A5:04:31:3C:4B ACL MTU: 1021:6 SCO MTU: 180:4
RX bytes:82105 acl:0 sco:0 events:1989 errors:0
TX bytes:516 acl:0 sco:0 commands:48 errors:0

hcidump -x does show Commands/Events received, beacons are being seen, and collected by our app.

> HCI Event: LE Meta Event (0x3e) plen 42
LE Advertising Report
ADV_IND - Connectable undirected advertising (0)
bdaddr F9:77:66:E8:F7:8B (Random)
Flags: 0x06

[Code] ....

However when the app tries to connect it always gets connection refused at gatt_connect.

gatttool behaves the same way, and hcidump does not show any connection attempts, implying no connection between gatttool and the device, although it is specified on the command line.

Finally although the bluetoothd is running bluetoothctl also shows no default controller found. I had edited /etc/bluetooth/uart.conf, adding an hciattach entry for the device but that changed nothing when restarting the bluetoothd. Entering a garbage entry into that file does not produce any errors, so I am not sure it is even being read.

Also systemctl|grep bluetooth shows :-

sys-devices-virtual-bluetooth-hci0-rfkill0.device loaded active plugged /sys/devices/virtual/bluetooth/hci0/rfkill0
sys-devices-virtual-bluetooth-hci0.device loaded active plugged /sys/devices/virtual/bluetooth/hci0
sys-subsystem-bluetooth-devices-hci0.device loaded active plugged /sys/subsystem/bluetooth/devices/hci0 loaded active active Bluetooth

/sys/devices/virtual/bluetooth/hci0/address shows the correct MAC, but /sys/subsystem/bluetooth/devices/hci0 does not exist, a post elsewhere indicated this was not a problem but that seems odd.

Is the uart.conf file still used([URL] .... would suggest yes) and if so is the format a full hciattach command or merely the hciattach parameters?

Debian Configuration :: Unable To Get Intel Pro/wireless 3945abg Connected To Router

Mar 2, 2010

I am unable to get my intel pro/wireless 3945abg connected to my router. The firmware has been installed and at first was even able to connect, but now the access point doesn't even show up in network manager. I am currently able to connect using a USB wireless adapter, but for certain reasons, would prefer to use the former. I've looked over this page with no results.

Debian :: Installer Not Detecting LVM ?

Jun 13, 2010

I'm having trouble getting the debian installer to detect an existing LVM

I installed Lenny on LVM on top of RAID 1.

My system looks like this:

I just added two 1.5 TB drives in raid 1 to the logical volume group home 100% added to /home /dev/md3

I went to reinstall the system from the lenny disc and now the installer does not recognize the LVM. It did recognize the LVM before I added md3 to the LVM.

During the partition editor, if i go to a terminal (by going to another window/console) and give the command vgdisplay it says that physical volume with UUID V0S1Yx-361r-NZaE-w1Fy-kCFQ-9MmH-g287vh cannot be found. You will see below that the UUID refers to /dev/md3 (the added 1.5 raid 1 array)

Below is the output of "pvdisplay" and "mdadm --detail /dev/md3"

I don't know if this has to do with it but /dev/md3 is the only array that says local to host yield [yield is my hostname] next to its UUID after the mdadm --detail command.

Debian :: USB Wireless Not Detecting Networks?

May 13, 2009

I just installed Lenny and I was getting settled in. The wireless didn't work, but I have this USB adapter and was going to use it as a stop-gap measure until I get the real wireless going, especially since I could use that connection for downloading, forum search, etc.However, the USB adapter isn't working either. It seems to detect the adapter itself, since the "appendage" that appears on the right-click menu appears, but there's no detected networks. I have Jaunty dual booting with Lenny, and I know both the network and the USB adapter are working, since I'm on the Ubuntu side using both right now

Debian Hardware :: Toshiba Chromebook Not Detecting Touchpad

Nov 19, 2015

I recently installed Debian Jessie on my Chromebook, and everything seems to be in order but the touchpad is not working.

I tried following the instructions in However the following command does not yield output:

Code: Select allegrep -i 'synap|alps|etps' /proc/bus/input/devices

So the problem seems to be that the kernel is not detecting the presence of the touchpad. Is there anything I can do to resolve? My kernel version is 4.2.0-0.bpo.1-amd64

Ubuntu :: Cannot Enable Compiz Effects After Using A Projector

Apr 7, 2010

A friend whom I turned on to Ubuntu with 9.10 recently connected a projector to watch a movie off her laptop. When it was connected, the laptop screen changed and it was clear that desktop effects through compiz were disabled. Thing is, since disconnecting the projector, I cannot get the effects back.If I go into Preferences - Appearance and click to enable Normal or Extra Visual Effects, the same thing happens. I.e. I get a popup saying Searching for hardware driver...and after about 20 seconds, the screen flashes a bit, and says

Desktop effects could not be enabled. Not sure why it's searching for a hardware driver. The computer doesn't require any 3rd party hardware drivers to be enabled - it doesn't have an nVidia card or anything like that.If it makes a difference, she yanked the VGA cord out without setting the display mode back to just her laptop with the FN and F key combo.I've tried:

-Reinstalling compiz

-Tinkering with options under Preferences - Display

-Ensuring that nothing is available under Preferences - Hardware Drivers

Ubuntu :: Communicate To A Sanyo Projector Using PySerial?

Jan 13, 2011

I am trying to communicate to a Sanyo projector using pySerial and am having issues. I have verified that my baudrate and parity are all set correctly. Here is my code (using COM13):

import serial
ser = serial.Serial(12)
ser.baudrate = 19200


I have also tried variations using "CR0", "CR0", "CR0x0D" and nothing seems to change it. I'm using another application to ensure that I can speak to the Sanyo projector, and I get a correct response.CR0 is a status read of the hardware that should return something like "80" which would mean "STANDBY"However, the responses that I keep getting are things like 3,4, or 5 which seem to be errors, given that they are returned apparently based solely on the length of the String I send, not based on the actual command.

Debian Installation :: Installing Stretch Stops At Detecting Network Devices

Oct 11, 2015

Installing stretch stops at detecting network devices. This is an attempt to install stretch over the top of Windows 10 on a Toshiba Radius 15 with 2 each USB2 ports and 2 each USB3 ports, and no RJ-45. Its wireless is based upon the Intel 7265. Just before the presentation of the wireless list, the system reports the need to install non-free:


and asks for media. Whether I respond yes or no, the driver selection screen comes up. [I have not been able to find those four specific files on the Internet.The network card screen comes up, I select the Intel recommended firmware iwlsifi, but the page just recreates itself and waits for a new selection. If I select either 'none' or 'not listed', the installation fails saying there is no network card.I have obtained from Intel their suggestion as of Aug 2015: iwlwifi-7265-ucode- placed this on a USB stick in a subdirectory labeled 'firmware'. This was built from Windows 7 on a FAT32 file system.

There is also a Dynadock docking station that connects to the Toshiba via a USB3 cable. Besides video, USB,and audio, this has an Ethernet port. I have tried this connected to the laptop but it also requires a driver. I have placed that driver on the firmware directory of the USB also.

Are the four files listed above somehow inside the iwlwifi driver tgz?Is there a way to get the docking station drive to load so I can use its Ethernet port?

I have used Rufus to build the stretch USB from Windows. I do have a a Linux box I built with the same USB. I would use it but so far, I only have a command line on it and I have not figured out how to access to download the installation files nor how to put that on the stick.

Fedora :: Back To Nouveau Driver - Display On Projector?

Nov 12, 2010

Fedora 13, x86_64, up to date. Trying to get nVidia Quadro NVS 140M to display on a projector the same as it does on the laptop screen, which is 1680 x 1050. I failed to do so with the nVidia driver (latest version), so I want to go back to the nouveau driver and try with xrandr. I have always used the nouveau driver with Fedora without an issue, but in my former life in Ubuntu I sometimes switched back and forth between the "nv" driver and the nVidia driver.

Doing so was trivially easy - just edit xorg.conf replacing "nv" with "nvidia" or vice-versa, then restart X. However, after installing the nVidia driver via Yumex and using the nVidia config utility, I find that now I have an xorg.conf file that is loaded with stuff I don't understand, except that at the top it says it was created by nVidia, and there are two places where it says the driver is "nvidia." I have searched and all I can find is instructions for installing the nVidia driver.

Apparently that is meant to be a one-way ticket, because I can't find any instructions for how to return to the nouveau driver. Except stuff that is over a year old, and complaints from users whose systems failed to start X. What would happen if I just replace "nvidia" with "nouveau" in the xorg.conf file and restart X? I know if it won't start X I can boot to rescue mode and re-edit xorg.conf, but I'd rather ask first and do it the right way than have to repair a broken system.

Ubuntu Multimedia :: TV Showing Us As Projector - Remove Overscan?

Jul 25, 2010

There's several threads dealing with overscan, but I've got an interesting twist in my setup that (I believe) is putting a kink into the proposed solutions. I'm trying to set up a media center PC with Ubuntu 10.~. The motherboard has built-in ATI graphics (3300 series), and connects to my television (Panasonic capable of 1080i) via HDMI. As can be expected, the overscan makes the top and bottom bars nearly invisible (as well as a portion of the sides).

When I run the Catalyst Control Center, it informs me that the monitor is a projector, not a TV. Try as I might, I can't convince the thing it's attached to a TV. When I run "aticonfig --tv-info", I am informed that a TV is not connected.

One question I could ask, though: does it matter? The reason I'm asking is that I can't find the "Configuration" menu option in the CCC that all the other threads talk about. I know where the little black triangle menu is, but there's no "Configuration" item in it. There's also (as best as I can tell) no way of adjusting overscan for a digital projector.

Ubuntu Multimedia :: Blurry Projector Image With Intel GMA

Oct 11, 2010

Here are the details:
Acer Aspire 5315-2681 notebook
Intel GMA 965 adapter
Ubuntu 10.04.1 (Lucid)
Not sure what resolution the desktop is, but should be 1280x800
Fn+F5 does nothing (2nd display notebook hotkey)
ANDsome sort of SHARP projector
Projector resolution should be 800x600

This is the info from lspic:

VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03)

(There is a sticker on the computer that says Mobile Intel GMA X3100, however.)

When I booted up the computer with the projector attached my bootloader appeared on the wall but not on the LCD. When I logged in my desktop appeared properly on my computer and is duplicated on the wall. However the wall image is very blurry. Part of the lower image is cut off and the right side is too short and there is a green band on the right edge a half dozen pixels wide.

When I booted (dual boot) into windows XP I got the same thing. Then I installed the proper drivers for the graphics adapter (they had not been installed because I hadn't used XP for anything but updating the BIOS) and the image lined up neatly and fit properly, and I could set the display to extend my desktop (instead of duplicate) it on the projector image. (This is what I would like to do under Ubuntu).

I'm concerned that my VGA controller doesn't have the right drivers or is set up incorrectly, but since I'm new to Linux I have no idea how to fix it.

Ubuntu Multimedia :: Screen Offset After Using Projector And Gtkwhiteboard?

Jan 30, 2011

Ubuntu 10.10Asus UL30Agraphic chipset Intel GMA 4500 MHDNative LVDS1 display resolution is 1366x768, but my laptop now boots at 800x600. Using xrandr to set resolution at 1366x768, I get the right dot pitch but the screen is still 800x600 px wide, left-top aligned on a 1366x768 display, so that I see a 168px black belt on bottom and a 566 black belt on the right. A vertical screen offset of 168 px affects also the pointer (touchpad) in the following way - I can move and see the pointer arrow all the display wide including the black region, but input (click) is taken for a position 168 px above the pointer visible position.

This is happening after having used the laptop with an external projector and gtkwhiteboard (wiimote based infrared pointer management). I then removed gtkwhiteboard to no effect.Everything works fine when booting in failsafeX, recovery mode. Here is output of uname -a

Linux bidolino 2.6.35-25-generic #44-Ubuntu SMP Fri Jan 21 17:40:44 UTC 2011

Debian Multimedia :: Radeon Stopped Detecting Proper Resolution In Testing-Wheezy?

Apr 19, 2011

I have a LMDE (Mint Linux Edition based on testing, now Wheezy) i386 that I just did a dist-upgrade on and now it isn't properly detecting my monitor resolution. I have two 1680x1050 monitors, one attached to the DVI and another to a VGA video switch. When I rebooted to the new 2.6.38-2-686 kernel both monitors were giving me 1024x768. I futzed around for a while and could then get the the DVI monitor to correctly identify the proper resolution, but the VGA monitor resolutely refused to see more than 1024x768.

I was able to get the proper resolution by entering these commands:


Should I file a bug report, and if so, with whom? I have to say, the Debian bug report process is not too newbie (or even not-so-newbie) friendly, but I'd like to help if it doesn't require me to hand-configure a MUA.

Also, I suppose I shouldn't mention it in a single post, but my mouse is behaving rather unpredictably now (click speed, selecting), and trying to reboot dismounts the file system and then starts up again giving me my display manager (in my case KDM), without restarting the system (both from "sudo reboot" and trying to restart with KDM or the Gnome widget). If I really want to restart the system I have to halt it first and hit the power button.
