You may also consider changing advanced options, especially changing the composting type. I cannot use OpenGL, hence my Compiz is useless.. I have ATI 5850s
General :: Use A Rs232 Device That Uses The Usb Port?
May 18, 2010been trying to use a rs232 device that uses the usb port. it calls for a virtual com port to be created. i am running on ubuntu 10 and get hella confused with the search results i have come across.some call for the usbdevfs which apparently doesn't exist under lucid. another had me do use some "magic" in getting it to work.they provided a script mountusbfs.sh
Code:
#
# Magic to make /proc/bus/usb work
#
mkdir -p /dev/bus/usb/.usbfs
[code]....
of course when i tried it the domount command doesn't exist so i modified the above script replacing the domount with mount and it seemed to do something things. usbview is specified as the determining factor whether or not you have the usbfs mounted properly. it wants to use proc bus and ubuntu doesn't use that anymore apparenlty. i have read that i need to enable a usbmon (flag?option?) in the kernel to be set. which it isn't when i followed the steps to check.
Fedora :: Wine/opengl/32 To 64 Bit - Cannot Load OpenGL When Try To Start WoW
Oct 19, 2009I just upgraded from FC8 (32-bit) to FC11 (64-bit). In doing so, I backed up my entire World of Warcraft folder so I could try to avoid having to download and install it all over again. However, I've now reinstalled wine (64-bit now), and the nvidia drivers from the rpmfusion repos (also 64-bit), and when I try to start WoW, it says it cannot load OpenGL. I'm wondering if anyone knows what's up, and if there's a solution that doesn't involve reinstalling WoW.

Feb 19, 2011We purchased a new database system at work last October, ditching the old system because of a lack of support from the vendor. This is a retail Point of Sale and Backoffice database system. I am not sure what system the new one runs on, but the system we replaced was a Firebird data base. The reason I am posting is because we are now in need of the information contained in the old database which was not completely imported into the new system.
Basically the problem is this: The database in on a Windows XP system and I found a copy of SQL Manager Lite 2008 on the system, which after quite a bit of studying, I figured out how to extract the database into a removable file. I have this file (178MB) on a USB stick in a file called Backoffice.fbd.
My studying suggests to me that I can get into this database with MySQL. I have never used this and have no clue how to do this. All I want to be able to do get into the database and create tab deliminated spreadsheet files for each of the database sections (Customers, Repairs, Sales History, stock files, etc.) Is it possible to do this with Ubuntu and MySQL and if so, can expert suggest one or two things to get me started. While a guided tutorial would be nice because I am not an expert, I am willing to learn on my own if someone could point me in the right direction.

The code compiles without errors, but doesn't catch any input text from the device attached to RS232. I have tried it with Rx and Tx connected, but didn't receive my text back. It works OK if I substitute /dev/ttyS0 with an ordinary file, but any attempt to use /dev/ttyS0 seems to lead to an empty answer string. I tried this on a PC under Ubuntu Linux 7.10.
Programming :: Transferring A Program Across Rs232?
Dec 16, 2009I've started development on a ARM board. The ARM board displays it's command prompt through it's rs232 output. So I open putty/minicom (rs232 display) and can see and interact with the ARM linux system through my PC. The ARM root fs is on a USB pen, So I cross compile on my PC, then plug the pen into my PC copy the exe into the home/usr etc folder. Then unplug. plug it into the ARM boot the ARM and from my PC rs232 window can run the code. However plugging/unplugging is taking an age, I'm sure there must be a way to transfer the exe across the rs232. I've tried to use putty minicom to do so throught various methods xmodem etc but don't seem to be able to. I think I must have to do something on the ARM end but am unsure what?

Aug 6, 2010I was able to write a script on Linux Shell for send and read data to a serial port. But I�m facing a problem now. If by any mean I send to de device anything else than the predefined strings, stated by the manufacturer, the device ceases to respond. The only way I found its to turn off and then turn on the thing again. Which its very impractical. Its there any way to "reset de UART chip on the device" or send some string based on the RS232 standard that clean the device buffer?

General :: RS232c And OpenGL In Same Program
Feb 10, 2010I am trying to write a program that accepts user input from the keyboard and a joystick and then sends out the data using the rs232 port of my system to other hardware. I need to send out about 10 bytes every 20 milliseconds. The thing is I need to also keep on reading data from the same port and display it on an opengl screen. This visualizes the hardware data coming in.
So the way I did it was by spinning everything around opengl..I setup GLUT - as follows :
/* register call back functions */
glutDisplayFunc(redraw);
glutReshapeFunc(resize);
glutIdleFunc(visualize);
glutKeyboardFunc(getkey);
glutSpecialFunc(getspecialkey);
And in the idle function visualize(). I currently do the joystick reading and rs232 packet sending and recv stuff. I also call redraw after I am done so if I have received new data above, then it gets drawn on the screen. Everything works fine except that calling redraw() from visualize() is logical in a PC simulation where the simulation state needs to be rendered on screen after a simulation step. But in my case it takes up too much time, much greater than 20 ms. So I can no longer guarantee I can send out packets through the rs232 port every 20 ms. What are my options here if I want to send out packets and visualize data at a reasonable frame rate - packets within 20 ms is more imp of course.

Programming :: Streamout Command To RS232 - Send Something Through Serial Port?
Aug 5, 2010I want to send something through the serial port, for example
[code]...
the point here is send some numbers to a couple of 7 seg displays, so I will wire a RS232 chip on a protoboard, the logic after the RS232 is not an issue, but how can I assure the data is being sent right from my linux box to the RS232 chip, the one on the protoboard? Do I have to write a C program to read the strings and then send them to the serial port?For example if I wanted to send this to the displays:
[code]...
So I guess the simplest way is (Supposing I can deal with the stream so it is filtered and only display the number array) $ ifstat > /dev/ttyS0 But, how do I know if the RS232 will take them as the right characters?

Ubuntu :: Can't Access HFS+ Data
Aug 25, 2010On my Mac, OS X Snow Leopard 10.6, I copied my itunes music files onto my external hard drive, which is HFS+ formatted (as FAT32 just wouldn't cut it for the other files that are on this drive, mainly 1080p video spanning several gigs on a single file)..
Here's the problem, Linux doesn't have ANY permissions it seems to access it.. I did nothing special on the Mac side, just drag and dropped all the files over.
As a normal user I can't open the folder. As root, I can go into the folder, but still can't access the files themselves!
I can't write to it either to change permissions because HFS+ is read only.
I need these files IMMEDIATELY, and I need to know how to do this now.
Normal user: [URL]
As root: [URL]

View 5 Replies View RelatedHardware :: Access Data From Old LVM Drive
Jun 12, 2009I have a server which had one drive in it that was using LVM. I removed it and moved it to the secondary bay in the same server, then installed a fresh new blank drive in the primary bay on this server.
I then installed CentOS 5.2 on the new drive. During the partition phase of the install, I partitioned my new drive and MAY or MAY not have removed the LVM from the second drive and left the partition there, not sure exactly what I did.
After install I wanted to try to mount the old drive so I could access the files on the old drive. The /boot partition shows up when I do a df -h but not the / partition where everything I need is stored.
When I look at the drives in Webmin, the second drive is there and shows up as LVM but has not LVM name.
Basically what I need is on /dev/sdb2.
How I might be able to mount this partition which seems to still exist when looking at webmin.

Fedora Networking :: Access Data Through SSH - Ethernet?
Jan 23, 2010A while back I've been playing with the idea of setting up one of my machines as some sort of data server and would like to access it through SSH. I've already conducted some tests through the wireless router and apparently on the software side there are no issues with the SSH thing. I also noticed that since the same adapter was in use (wireless) SSH 'fought' with the Internet for the bandwidth
In order to avoid the aforementioned problem and also in the spirit of enhancing security I am thinking of setting up the following network scheme with two laptops and two routers (a wired and a wireless one):Both laptops would receive the Internet service through the wireless router. Both laptops would be connected through their Ethernet ports to the other router. The wired router wouldn't be connected to the Internet. Would this set up allow me to use SSH only through Ethernet thus eliminating possible bottlenecks in the wireless network? I am operating in the assumption each machine would have two different IPs (one per router), is this correct?
For some weird reason (default network device?) when I connect the Ethernet cable to the laptop, although NetworkManager claims to be still connected to the wireless network, I can not connect to Internet (the wired router has no Internet BTW). But if I unplug the Ethernet cable the Internet continues through the wireless network.
