Keyboard response in console
« Thread Started on Dec 7, 2011, 5:13pm »
I am seeing a very weird issue and would like others to check.

The keyboards (plural form) in console are not very responsive.

Say I do a ctrl-alt-F1 and drop to console, typing is hit or miss. Sometimes I have to keep pushing a key until something comes up. That is bad for entering passwords.

I thought maybe my keyboard is bad so I went upstairs and used another machine that also has Saline. The result is the same.

As soon as X starts, these keyboards fly.

So this is either a bug or it is particular to my install. What I have been doing is to create a master install on a 8GB flash drive. I then use that flash drive to install onto other machines, thanks to the true live install feature in SalineOS. So it could also be a problem in my master install.

It is a strange problem.

Thanks,

Just rebooted, Ctrl+Alt+F1 at login brought up console, logged in with password and no stutter in keyboard. If you have a copy of your .iso you might do a md5sum check. I am using SalineOS 1.5-64 bit

I am using the 32bit version.

Sorry I do not have the DVD anymore. I downloaded the iso and wrote to a flash drive using the dd command.

I was trying to generate a xorg.conf file. It seems like "sudo service gdm stop" is not the command for me to run Xorg -configure. Was it "slim"?

Thanks,

We are using slim, not gdm. If you are using remaster to make the installer then Anthony might know what went awry.

Yes, I did use remaster at one time.

I tried stop slim but the log file xorg.x is still locked by the system so Xorg cannot generate xorg.conf.

It is no big deal as I was trying to reverse the primary and secondary monitor. I have this dual head graphics card that has a DVI and VGA output. SalineOS always selects the VGA as the primary and WinXP always uses DVI as the primary. It cannot be changed in WinXP as that option is greyed out so I was trying to change in SalineOS to make them consistent. I have made a few scripts and added some icons to wbar so I can switch the monitors, although this is not an automatic (on boot) solution.

The reason I still boot into WinXP is because somehow Linux (not just SalineOS) is still a bit weak in the video playing department compared to WinXP. Be it Youtube or playing 720 or 1080 video files, WinXP always gives better and smoother performances on the same hardware, which are on the borderline to meet the minimum requirements. It is a graphics driver issue but after all these years, it is still an issue.

Our univ sold a lot of the late Pentium 4 machines for very cheap so many faculty and staff bought some. Typical specs are P4-2.8Ghz, 1 - 1.5 GB RAM and the Intel 865G on board graphics card. With WinXP, full screen youtube and downloaded 720 video are very smooth. Downloaded 1080 is barely watchable but not smooth.

On the same machines, SalineOS, Linux Mint, Ubuntu, and even Puppy Linux all gave about the same performance. Full screen Youtube is watchable but not as smooth as in WinXP, downloaded 720 is smooth but downloaded 1080 is not watchable.

Thanks,

Start terminal and run:
Code:
man slim

for the commands.

On my daily use installs I always use sgfxi to install the latest graphics drivers and never have a problem with the keyboard being slow in the console. You should try simply killing SLiM in order to drop to the console, issue the following command as root:
killall -KILL slim

Thanks, Anthony.

"killall -KILL slim" gives me a very responsive keyboard. This serves the purpose.

Very interesting that "ctrl-alt-F1" does not.

I am fairly certain that it isn't only the keyboard that is slow, it is the entire machine. The machine is busy writing a never ending loop to the Xorg log file.

Sometimes I have similar problem caused by dvb-t stick driver. In dmesg it complains about too old kernel. But when I try to install newer one synaptic wants too remove the old one and remastersys. Anyone knows how to go around this? I don't mind even if I have to create Saline iso with backported kernel from pure debian for my own, but I don't know how to do that ::)

Well, you really can't get around this. Remastersys is a very complicated script, and the last stable version requires the exact boot scripts and kernel that is used in Debian Stable. Upgrading the kernel will break Remastersys, so you have the option to keep the current kernel or upgrade the kernel and remove Remastersys.

Thanks. Is it safe to remove remastersys? Nothing else in SalineOS depends on it?

SalineOS utils does, but everything in SalineOS utils is only truly useful on live disks and getting the system up and running. After the system is running they aren't all that important and can be removed without losing anything important.

Curious. I just removed Remastersys and it didn't pull out SalineOS-Utils.
Just checked and salineos-utils v1.5 is still there. fsarchiver works fine for backups.
Really need a larger hard disk. That's my next goal, :) for the holidays.
