Hey,

Currently using Slackware on a AMD 2600+ x64, 6GB RAM. Video card is a NVIDIA 8500GT.

I've been downloading the drivers multiple times for about an hour. I know how to install them and how to run the packages but I keep getting failed checksums, though the range of the failures vary each time I download?

Any fixes?

Cheers.

We can't be sure the checksum you have is correct or not.

If normal files work then I'd assume that this is either bad at source or has faulty sum value.

Any suggestions?

That's like the 10th time I've downloaded it but it always cites different checksum errors. The drivers that came with Slack actually work ok (even with effects fully on at 1080p) but it lags and stutters occasionally so it wouldn't hurt to have the latest NVIDIA drivers.

Maybe the lagging and stuttering has to do with something else, maybe disk I/O. What filesystem are you using ? Try using the mplayer -cache option if you use mplayer. Also make sure to use the vdpau drivers. Note that you have to install them yourself because they are not included with nvidia anymore.

I downloaded and installed the latest drivers and there was no checksum error.

Filesystem is ext4 I believe. I just used the default on setup. My HD is a 600GB SATA. I also have an 8GB swap partition, and home partitioned to 60GB. Main Linux Partition is 100GB.

I just downloaded NVIDIA-Linux-x86_64-270.41.19.run and checked it OK:
so the problem is specific to your system including the network connection (expected, really). If you checked the same downloaded NVIDIA-Linux-x86_64-270.41.19.run several times, are the numbers in the error different? Have you tried saving to another storage device such as a USB stick?

I belive the issue may be the signal to noise ratio on my internet cable.

Thanks

Maybe the cable is damaged. Try another or test it.

If you checked the same downloaded NVIDIA-Linux-x86_64-270.41.19.run several times, and got different numbers in the error the it would suggest it wasn't the cable. If it was the cable (or something else in your Internet connection) then download speeds for all TCP connections would be would be low as TCP packets failed checksumming resulting in re-transmit requests. IDK how to check TCP packet checksum stats (there will be a way) ...

And yet tcp/ip has checksum built into it.

Might see if you could use a download manager. Or use different format. Some web pages also open as ftp or http.


See if it is on a torrent.

Hi,

What are you using to download?

I've gotten checksum errors when hardware was faulty, either RAM or the HD itself.

Check the md5sum of the file yourself -- 2,3,4x -- just to make sure it does not vary. If repeated md5sums are generated differently, this is an easy to spot sign of hardware trouble. You could run memtest, check dmesg, and smartctl just be on the safe side.

Use wget the continue option to obtain the file. Theoretically, you could wget the file multiple times until it's complete. Here's the direct link for the latest stable x86_64 driver with compat32 option

You should know if the problem is with your Internet connection, as most downloads would fail, and you'd have an altogether poor surfing experience.

Sorry to repeat some of what catkin posted -- but it is good info
