Jan 4, 2011df -h [URL] I did the following command to find everything is in /usr or /var, then tracked it down to /usr/lib and /usr/share as the main offenders, but out of all the directories none are more than 1mb or so.

I tried to uninstall firefox, which is what got me in this mess in the first place, the log claims it will remove ~240 mb but failes on a "E: Write error - write (28 No space left on device)" [URL] If I could juggle something onto an external hard drive so I can uninstall firefox I would be out of the wood. Failing that I believe a new install is in order.

Programming :: Write USB Device Driver?
Oct 11, 2010I know, I know..."How long is a piece of string"?
I have one of these devices:
[URL]
Of course, it's Windows only, and XP only at that. However, the data that needs transferred between the device and the computer should be fairly basic, unless it offloads a lot of processing to the computer. I'm not a programmer, nor do I play one on TV, but I have written some fairly complicated microcontroller programs and some basic Java GUIs. Besides writing the actual code, how hard is it to do whatever needs done to make a Linux device driver, apart from the code to make the device work?

Jun 21, 2010I have a Asus eee box eb1501u running Kubuntu 10.04 LTS (32 bit) and I am trying to get the remote control to work. Many guides for example this one http://wiki.xbmc.org/index.php?title...eeBox_PC_EB150 first states that you should run code...
Before I removed the Windows 7 installation I tested the remote in Windows to make sure it worked and it did. I cant see that there is a possibility to turn on or off the IR-device in the bios settings!? I would really like to make it work in Kubuntu to. I'm pretty n00bish at Linux but I think I can figure it out if someone would point me in the right direction.
Ubuntu Multimedia :: Using External MIDI Device To Control Jack Transport
Oct 16, 2010I'm new to ubuntu but i do have a basic understanding of programming, but nothing too serious. The reason I am mentioning this is because I have a little project. Currently I use JACK to control the transport of all the aps i use to make music with ardour, hydrogen and rosegarden mainly. I also have an external midi drum machine that I sometimes hook up into the mix via midi in/out, my drum machine (yamaha ry to be exact can send and receive midi data. My question is can I use the transport controls on my external drum machine to control JACK's transport controls? If there is already am app that does something like that, excellent!

View 1 Replies View RelatedGeneral :: Make The Root Device Read/write?
Mar 4, 2011I need to change a filename but when I boot up I get the message root device is read-only. Is there a way of changing this so that I can change the filename. I have a Mac Pro running Leopard OSX. The graphics card an NVIDIA 7500GT or driver has failed. It was suggested elsewhere that I change the relevant kext files to filename.kext.old, which I did, now when I try to boot start in OSX I get a message in various languages telling me to restart. I have tried booting in safe mode and from original Installation CD. In Safe Mode I get the same multi language splash screen, from CD I still have the graphic card problem, screen freezes and artifacts appear. So I boot up straight into CLI by holding down CMD-S hoping to be able to change filenames back but it says device read-only.
View 2 Replies View RelatedProgramming :: Block On Write Call To TtyACM Device
Nov 1, 2010I have a write call to a ttyACM serial device that blocks after several hundreds bytes are written.I'm writing in ~25 byte chunks, so I have 5-8 successful writes, then the next write blocks forever.I can bypass the blocked call using select, but I can never call write again without closing and re-opening the port.
The serial port is opened correctly because I can read from it just fine. Write permissions are correct, and it's opened RW.The code is likely correct because I tested the same code using the same device on a pure RS-232 serial port, and it worked fine - no block. Is there anything to know about the linux ACM module?It's my understanding that write calls basically shouldn't block.They're supposed to return -1 if there's an error.
Programming :: Fail To Write To USB Device Boot Sector / What To Do?
Jul 4, 2010I'm writing a C program that reads the boot sector of a USB disk. (it is mounted as /dev/sda1). I'm able to read the sector, by the calls code...
The problem is when I wish to write. I use the call:
bytesWrite = write(fd, buf, 512)
The 'write' returns the value of 512, which looks as if the write was successful, yet
when I read again the /dev/sda1 device, I see that no writing was actually made.
Can anybody tell me what do I need to do in order to allow an actual write to the
device?

Jul 30, 2011My wife is purchasing a netbook with no internal CD/DVD writing device, so we plan to purchase an external CD/DVD USB-2.0 read/write device. Our local PC shop has the following 3 external USB-2.0 DVD read/write devices:
(a) Samsung DVD-Burner SE-S084F/RSBS [not listed on Samsung site - too old ? ]
(b) LG DVD-Burner GE24NU21 USB2.0 [not listed on LG site - too old ? ]
(c) Super-Multi Portable DVD Rewrite (GP10 Lite USB2.0 Slimline) GP10NB20 (mentions Mac OS/X support, which is encouraging)
None of those are listed in the openSUSE HCL. Has anyone successfully used any of these with GNU/Linux (my google surfing on this revealed no GNU/Linux complaint nor any success stories) ? Or is there another such external USB-2.0 read/write DVD burner device that is recommended ?
OpenSUSE Install :: How To Browse 11.3 CD - Block Device Write Protected
Jul 15, 2010I can browse the iso image easily enough with a loopback mount, but when it comes to mounting the actual CD (which I did first), I get:
Code:
$ sudo mount -t udf,iso9660 /dev/dvd /mnt/dvd
mount: block device /dev/dvd is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/dvd,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
/var/log/messages isn't very helpful, either:
Code:

View 3 Replies View RelatedSlackware :: Optical Drive Not Identified - Get Permission To Read / Write In The Device
Aug 6, 2010On one of my machines the DVD/DVDRW/CDROM drive appears as /dev/hdc and is not identified as an optical drive by HAL. It is owned by root: disk and thus no users get permission to read/write in the device (not even those in the cdrom group). This stops playing DVDs, ripping CDs, no notifications appear when a disk is inserted, etc. etc. When I set the permissions for all to read/write from the device then users can access but still no notifications are shown.
On all my other machines the optical drive is identified as /dev/sr0 and is owned by root:cdrom . All have Slack 13.1 . Previously with Slack 12.2 this machine still had the drive in /dev/hdc but the permissions were right (I think because I added it to /etc/fstab with options for users to access it). I believe the problem is down to HAL not setting this drive to the correct group, but how do I fix it? I hate HAL, it has a mind of its own, just like in the scifi movie

Debian :: Sound Not Card Configured - Error 'Volume Control Did Not Find Any Elements And/or Devices To Control" - Driver
Feb 8, 2011Laptop is Dell Latitude C600/C500 with Pentium III 850Mhz, 256Kb L2 Cache, 256MB RAM, ATI M3 video card, HD 20005 MB and sound card is EES Maestro 3i. After trying to do something with Windows 2000 which was installed on the machine, I decided to put Linux without keeping windows on the machine. First I try with Xubuntu (latest version) which was working but slowly, then I found that Debian could work fine on that machine. I have installed latest version 5.08 and was surprised how goodly old machine can work. I solved problems with screen resolution (change from 800x600 to 1024x768) but I couldn't find solution how to fix problem with sound.
Actually I don't have sound on the machine. I looked for a linux driver for that sound card and Dell is only providing windows drivers. Then I found that I can solve the problem with ALSA drivers but I couldn't find the easy way (or any way at all) to install drivers and to get back the sound. When I click on 'Volume Control' (top right corner of the screen) I get the message: 'Volume control did not find any elements and/or devices to control. This means either that you don't have the right GStreamer plugins installed, or that you don't have a sound card configured.'
