I've just installed ubuntu 10.04 on a Lenovo Thinkpad Edge. Problem is that it generally doesn't detect the USB memories that I've been trying to use. On two occasions it did in fact detect the flash memory, but it couldn't open/read it for some reason (USB memories works on other computers), but all the other times the USB flash memory didn't even show up in Nautilus.
I am no techie so I'm not sure how to check what the problem is here. I've been googling it but either it refers to some specific stuff that doesn't cover my case or it simply is too technical for average users like me to understand.
I am new to C and linux. My code below does arbitary writes but I cant figure out where or how it does it.
I am calling the insertNode() function with seq = 'MISSISSPPI$' and alphabets = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ$'
Code:
Weird behaviour I should mention is that when I check for NULL pointer in node->child[index], the unassigned values are not null anymore, they point to arbitary memory.
This is my first post in these forums. I'm still quite new to Linux (using Mint 9) so please bear with my not-very-articulate question(s)When I boot up and open up a tty terminal I get a message saying "Memory corruption detected in low memory." I've done an extensive google search about the issue and it seems not uncommon. I ran a memtest with no errors returned, so I'm sure that there's nothing really wrong with the memory; apparently it's a bug in the kernel that's causing this.
When I am trying to run my application on RHEL 6 (Kernel 2.6*), I am getting the following error.*** glib detected *** ./corenms:malloc(); memory corruption : 0x086691d0 ***
I have a usb flash drive that is working/formatted etc however it's not detected after a reboot not even in lsusb, I have to physically remove and reinsert it, any ideas what could be wrong?
For quite a while I didn't have any problems and everything worked just fine, until I had to upgrade to KDE 4 from 3.5. And that, as you understand, required a major upgrade of quite a lot of stuff (not only the GUI, but also some of the system including the kernel). After I spent a while fixing up the mess (it works ok now, mostly), I still have quite a problem with optical drive and external disk detection.
Problem 1. DVD drive. Sometimes it works fine without any errors - the system detects the drive and can write and read the mounted DVD (that's exactly how it was before the upgrade). And sometimes (or should I say most of the time?) there is no drive detected.
Problem 2. Flash drives. I connect a flash-disk. It gets get detected, mounts automatically - yahoo! But.If I start the system with the drive already connected, then the device is not even recognized (doesn't appear in /dev). So I have to replug it.Used to work fine before.Something tells me that the problems have a common cause. Correct me if I am wrong. Please help!
Firefox's Plugin Finder Service says that it is an unknown plugin when visiting pages. I have tried the manual install using rpm and yum along with trying to uninstall and reinstall via Add/Remove Software.When looking at Extensions within Add ons, Flash is not shown on the list.
I just installed F11 and am trying to get flash to work in firefox. I installed the adobe repository and ran: yum install flash-plugin The install completed but when I try to run flash in firefox it says that flash isn't installed. How can I fix this?
how to format flash drives in ubuntu. In windows there was a "format" on the right click menu but I did not find one in ubuntu. i am using ubuntu jaunty.
i want to use sdcard as flash memory to port linux(uclinux) image , so that i can boot using my arm7(lpc2148) microcontrollerIn other words, can we use sda card to dump linux image and boot from microcontroller)
I stupidly unplugget my USB-cable, which was connected to my Nokia music phone, just as if I were in Windows. What do I do? I've lost my music on the phone, or, it seems it may be there (the correct mass of data), but my phone now tells me there is no music... Can I recover this? And - what is the correct way to unplug a USB unit in Ubuntu? To make it work, and find the phone/drive - I just typed "sudo lsusb" in the terminal, and it found and opened the memory automatically... How should you unmount the USB, and maybe even how do I get my data back?
Using 10.04 Netbook version. I am finding on my Asus EEE 901 that sometimes file copy just seems to freeze - seems to happen usually when copying from the built-in SSD memory to the plug-in SDHC memory card. I have tried reformatting the card and using a different card. It is not just this computer since I found the same thing on my last Asus which was the 900 model.
I am told that there are issues with Nautilus. Is there anything which can be done to improve this or is there anything else which I can install besides Nautilus? I am assuming that there is some issue related to Ubuntu's handling of SDHC memory cards.
It is becoming annoying because it seems to work sometimes and then not. When it happens only option seems to be to turn the netbook off and on again. Even if the file copy is cancelled the card seems to be unaccesible until rebooted.
Also after a certain point it seems that when I try and copy new files to the card, they appear to copy ok but obviously are corrupt in some way - when you try to play videos for instance they are faulty.
how to calculate (if possible) the end address of an image file in a flash memory. I'm trying to create a checksum and checkheader function and the info that I got is the file's offset, how many sector it consumes and its size. I kinda need the end address, sad thing is, I don't know how to calculate it.test.img's start address is 0, the size is 0x20000 and consumes 3 sectors.
Looking for a card reader/writter that will support most current card types. I am running Fedora 12 x86_64. Are there any gotchas, that I need to watch for? Also, Internal vs. external, any benifits of one over the other, or is it just personal preference?
I used to be able to write to my SD memory card but just recently it is being automatically mounted as read-only. I checked the read-only tab and tried to set it to the lock position, and to the unlock position. Neither position makes a difference. It was working normally a few days ago. I also tried changing the permission using su
ls -lt gives the following result drwxr-xr-x 4 col root 16384 1970-01-01 01:00 CANON_DC chmod chgrp and chown in su mode don't change anything either.
I tried mounting a different 1GB SD card and it works perfectly. I noticed that when I mount this card I get a window asking me what I want to do, but I don't get this on the other card. It must some kind of setting related to the unwriteable card.
If i have a shell script to run on a Linux unit, which has a command to Reset(or say upgrade) the unit in between the script.Is it possible to find out the memory address of the next waiting command so that i can store the address to any environment variable in flash , then after Reset will continue Run from the stored address.
Before buying an SD memory card, I'd like to know something more about the CPRM protection, in particular:Does CPRM influence the way I am supposed to access my own data? That is, does CPRM encrypt it? Could CPRM prevent me from accessing my own data?Is it possible to disable or eliminate CPRM from either the memory card or the card reader?Are there manufacturers selling CPRM-free SD memory cards?Is there any real alternative to CPRM-protected SD memory cards beside USB flash drives?Is Linux support for SD cards good?
I have a flash memory stick which according to GParted is "unallocated". As such it does not appear in File Browser or Gnome terminal. How can I get it to function? I don't mind formatting it but it is not showing. GParted will not let me change anything.
I have a Transcend 4GB USB flash drive that suddenly stopped working. However, when I insert it into the USB slot, the light on the drive glows, but I'm unable to mount the drive, neither does ubuntu detect it.I disconnected the flash drive, and then run `dmesg | tail`. The result was this :
[ 623.940610] scsi7 : SCSI emulation for USB Mass Storage devices [ 623.940928] usb-storage: device found at 6 [ 623.940931] usb-storage: waiting for device to settle before scanning
RAM for older machines like I use is fairly cheap these days. But flash memory is just as cheap or cheaper. So I'd like to ask about the feasibility of expanding my system's memory using flash memory. And about whether creating a partition for swap on the flash memory, or whether a swap file on the flash device, is the better way to go.
By flash memory I have in mind mainly USB sticks or what are sometimes called "pen drives." But I do also have CF and SD cards that, with the proper cheap adapter (one of which I already own for adapting CF) could be used to create extra swap space. So, what is the current consensus on the feasibility/advisability of using flash memory for swap? I've read about the limited write cycles of flash being an argument against using it for swap. But recent reading indicates to me that the limited write cycles problem applies mostly to older, smaller-capacity flash memory. Some will come out and say that, for larger-capacity flash memory, the life of the device is likely to exceed the amount of time your current computer will be useful (I think I've seen estimates in the range of 3-4 years life--minimum--for newer, higher-capacity flash memory).
A more persuasive argument I've heard against using flash memory for swap is that access times for these devices can be much slower than SATA, and maybe even IDE, hard drives. That would certainly dictate against using flash memory for swap.
So, how about some input on this issue? Anyone using flash memory for swap? If so, what kind (e.g., usb stick or SD/CF)? Are you using a swap file or a swap partition? How's system performance? Likewise, has anyone had flash-memory-used-as-swap die on them? The consequences would undoubtedly be dire. Also, has anyone measured flash memory access times to confirm or refute claims about slow access times? Are some types of flash memory better/worse than others in terms of access times?
I tried to install OpenSuse 11.3 on my brand new pc, which already had Windows 7 proffessional in it, and I went step by step through the installation without changing anything. It didn't work. I tried for a second time and this error message kept popping up: "Creating device modes with udev 2.0436224] [drm: i915_diver_load]*ERROR*Detected broken BIOS with 262140/2644kb of video memory stolen. 2.0436224] [drm: i915_diver_load]*ERROR*Disabling GEM(try reducing stolen memory or updating the BIOS to fix)"
And then a lot of letters and numbers wich make no sense to me. Now the only way I can initiate OpenSuse is with the OSuse boot dvd and on failsafe mode.
I am trying to install Ubuntu 10.10 from a USB flash memory stick. It works fine until around 95%, where I get the following warning/error:
[Code]....
I click OK and the installer seems to finish nicely, except the terminal throws several errors along these lines (see photo):
[Code]....
I tried also with 10.04 LTS, the difference being that the install warning appears two or three times instead of once. Some results from googling (Ubuntu Forums, Ubiquity bug) suggest unchecking the initial update options. I am going to try this but I'm not sure if I'll be able to get the boot loader right (there seemed to be problems with this).
I have a computer with 16GB of ram. At the moment, top shows all the RAM is taken, (NOT by cache), but the RAM used by the various processes is very far from 16GB.I have seen this problem several times, but I don't understand what is happening.My only remedy so far has been to reboot the machine.
