I know the tool system-config-display can tell me all about my display but it's not available on all systems and so I'm looking for alternative ways to get my monitor type. Ideally, I could just look in /proc but I don't see anything there and I would like to be able to do so from a script perhaps written in bash or perl. Is there some place to get this info, say in a config file somewhere?
View 2 RepliesAs per these instructions, I got up to the end of the "Acquiring an Ubuntu filesystem" step (where it asks you to mount the newly created Ubuntu partition) and ran into a problem: The partition won't mount, as the file system type cannot be determined because I cannot remember the file system used during installation. Is there any command that prints the file system type of GPT partitions?

View 2 Replies View RelatedI have Fedora Linux 13 64bit system. I use System Monitor to check which process is taking how much memory and cpu. Normally I have dozens of Chrome and Firefox windows open. The Processes tab shows which process is taking how much cpu/ram resources but I unfortunately there is no option like right click and make the window active that matches the PID (the one process that I have currently highlighted). Usually there is a chrome process taking up 30 or 40 percent of CPU while dozens other chrome processes taking much less cpu. I must determine which chrome window ( or any application which has multiple instances running) is taking that much CPU time. So can some one help me to solve this problem?

View 1 Replies View RelatedI am writting a script to allow uploading of certain files. I want to limit the files by their filename and mime type, and by making sure the two match up.The first thing I need to do is make sure I've got all the mime types I need added. I have never done this before, but I understand that 'file' (which is what PHP's mime-type finding is based off of) uses magic databases that tell at which point in the file should have signatures of the filetype.
My trouble started when I was unable to determine the filetype of any of my video files. Currently, I have some .MOV and .MP4 files that I am using to test.
I have a cheap usb kvm that doesn't pass the EDID data back to the computer from the monitor. And now Fedora 12 seems to rely on autodetection of the monitor to start up at the proper resolution. When I have my samsung 712N on the kvm, fedora 12 boots to only 800x600 max resolution. If I connect the monitor directly to the computer video card, fedora sets the screen resolution to the desired 1280x1024 properly.
When booted through the kvm, fedora won't let me detect or select the correct monitor, and I haven't found any way to work around the problem other than pulling the monitor off the cable, connect to the cpu, reboot. After it's booted I can reconnect the monitor to the kvm and the video is fine.
My question is does anyone know how to manually tell Fedora 12 at startup what kind of monitor I'm using and skip the bootup monitor detection? So far I've spent a couple unproductive hours with google to discover this isn't a totally uncommon problem and no site I've found seems to have any solution.
I just installed Natty (11.04) on an old computer for my disabled brother with:
* Video Card:
00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01)
* Monitor:
VGA Mitsubishi Diamond Pro 750SB (old CRT monitor)
The problem is that when I select System -> Preferences -> Monitors, the monitor is shown as unknown and it only allows me to set 1280x1024 (shows 0Hz as display refresh rate) which is way too high for my brother. I was wondering if there's a way to select the proper monitor from a list so all display resolutions are shown and I can select a lower one for him.
OS: Fedora 12
Video card: ATI Radeon 9200 series
Monitor: ViewSonic 19"
I installed Fedora 12 configured Gnome automatically. Generally default settings. My monitor was connected directly to the video card and all was good. My video card was detected and my monitor was detected as ViewSonic Corporation 19" and I can set the screen resolution to 1280x1024. I had no xorg.conf file, as it seems that Fedora 12 does a great job of PnP to just set everything up.Now I go and complicate things by hooking up my monitor through a KVM switch. All of a sudden my monitor is "Unknown" and the best resolution I can achieve is 800x600.
Sure, I could go and reconnect without the KVM, but I want to be able use it.Is it possible to edit xorg.conf to tell it "Trust me, just use 1280x1024 at 60Hz even though you can't figure out what the monitor is"?
I tried a number of the posted suggestions to generate xorg.conf files but none of them get me what I need. A simple sample file listing that does the minimum is greatly appreciated (I can experiment from there once I get a basic setup working).And can someone explain if it is X or the ATI driver that is getting confused by the unknown monitor type. It helps to know what is actually going on in addition to a fix (so I can figure it out myself in the future). Thanks!
I have a display problem since updating to Slackware 13.37. Everything was fine on Slackware 13.1, but when I switched to 13.37 some piece of software came up with the wrong monitor size. I have a 1600x900 LCD monitor but the X screen came up as 1024x768 with blackness on either side of it. Under Slackware 13.1 the X screen came up as 1600x900 as it should without any prompting from me; I didn't even have an Xorg.conf file. I tried using the Xorg.conf file which was needed and work for older Slackwares, eg 12.*, but it didn't work. (Saying it didn't work is a gross understatement! That old Xorg.conf completely screwed up mouse, keyboard, and monitor; the screen was flashing and nothing worked. The only way to get control back was to SSH into the machine from my laptop and reboot. Killing the X server via that SSH console did NOT the flashing or get me back to my console login; only reboot worked.)
I find I can get the screen to be the right size manually by going through KDE's "System Settings" --> "Display and Monitor" --> "Size & Orientation", then disabling "LVDS1" and setting VGA1 to 1600x900. The size of my odd-sized monitor is being correctly detected for the "Auto" choice. Upon reboot LVDS1 stays disabled but VGA1 reverts to 1024x768 so I have to do this each time.I've done some search of the on-line literature regarding the error messages I am seeing in the boot log.
People are suggesting changing all kinds of things to alleviate the side effects of the "conflicting" error message above, even modifying GRUB parameters (which won't work for me since I use LILO).So, I have a manual work around which I must do each time I log in. Does someone know how I can get X or KDE to force 1600x900 upon start (while Linux/X/whoever find and fix the problem) or does someone know of a real fix?
My system doesn't reacts at writing values below 255 to /sys/class/hwmon/hwmon0/device/pwm(2,3) which correspond to 3-wire case fans connected via M/B (ga-890gpa-ud3h) headers. The idea was taken from [url]
ls /sys/class/hwmon/hwmon0/device/
It indeed shows the actual speed:
But refuses to write to fanX_input: permission denied (even for root).

I do not run any daemons for fan control, but suppose the speed may be set by CPU in-kernel governor. How to stop a fan under this conditions without doing hardware tricks?

I have a USB modem and a large C++ application that needs to detect whether that device is present or not. I was hoping to get advice for what the best method to do so would be. The only solution I've thought of is to parse the output of lsusb and look for the vendor and product ID of my device, but that seems a little hack-ish and inefficient. Is there a command or program that I can provide it a vendor/product ID for a USB device and it can tell me whether or not such a device is present in the system? Or another, better way to detect the device than parsing the lsusb output that I've been thinking

I need to generate pdf documents programmatically using Ruby. i.e. I don't want a GUI interface but an API interface. The bulk of my document is text but there are images included as well. I've looked at this thread: [URL] and it's 2 main recommendations PDFEdit and ImageMagik. PDFEdit has scripting available but I can't get my head round how to call this using Ruby. ImageMagik has a number of Ruby wrappers and is the kind of thing I want but as far as I can tell it only deals with Images and my stuff is mainly text.
View 1 Replies View RelatedIs it possible to do the following in C/C++ in Linux:Without direct linking (my program should NOT depend on Qt or GTK), display a GTK or Qt based file dialog.The behaviour should be something like this when my program runs, when you want to open a file:The program scans whether you have Qt installed. If so, it somehow manages to link itself to Qt (e.g. dynamically loading the .so file) and display its file dialog and get the path from it. If Qt wasn't found, it tries the same with GTK. If that also wasn't found, it displays a less powerful replacement dialog instead (better than nothing).
Or is there any other simple way in Linux to get a standard file dialog somehow (similar to when compiling for Windows you can very easily get its standard file dialog, no matter what version of Windows, in your code, even if your program doesn't use any other Windows GUI at all).
I am writing an application that has a web service client on a Windows PC that needs to call a web service on a Linux server. In order to create the client, I need to be able to programmatically read the WSDL on the server and use it to create the client. I'm using the web tools in MyEclipse to build the client.
The Linux server is running Red Hat, I believe, with ssh enabled. I can connect from Linux to Windows with no problem, but I can't reach the Linux box from Windows. I get one of three errors when I try: no path to host, connection reset, or unknown error number, depending on the port I use. I've googled for an answer, but haven't found anything yet.Is there some way to add the Windows IP to a permission file on the Linux machine so it will be recognized when it queries for the WSDL?
I wonder if there's a way to capture the same information I can get from nethogs to a file. All I need it per process (rather than per interface) what is the sent/received traffic.
