I Need To Increase Keyboard Buffer Size To Allow Key Strokes At 6000 WPM

Hello to everyone!

I was working on a linux server before few weeks. There was a grub/keyboard issue. If no keyboard is attached (ps port) the grub isn't loading the operating system. If the keyboard is attached the grub is loading the operating system by default without any keyboard interaction.

The difference is only that there is a keyboard attached. Thats all.

I was searching on the web and one thing came along: "turn on/off 'stop on errors' feature in your bios.". Maybe its this, but tonight I'm not able to check if its this becuase the server is in a remote location.

However I would like to hear what you think of this problem.

Have a good time!

I'm using a Swedish keyboard and switch to English for certain terminal commands. I use English as the system language. In both mint 13 and 15 I was able to keep the Swedish layout after restart; now I have to set the keyboard to Swedish after every restart. In 15 it was possible to have a persistent keyboard layout which differed from the system language. I think it was throught regional settings. In 13 I seem to remember using a command from the terminal which I can neither remember or find. Its not a big thing to set the keyboard layout after restart but its rather annoying. Any suggestions?

I want to show keyboard layout and selection of language at login screen in RHEL 7.

I have modified the language menu to show "show keyboard layout" and "Region & Language settings".
On clicking above menu items, applications are launched but they are not visible at login screen.
I check the programs are running by taking a remote session.

gkbd-keyboard-display -l us
gnome-control-center region

above two applications are executing but none is displaying at login screen(gdm).

How can I bring the applications at top of display manager(gdm).

I'm a new linux user. I also use Windows 7.

I write in English & French using the USA International Keyboard on Windows ... this works well with 'overstike' (eg, '+e = é). I'm sure there's a linux term for this.

I don't mind making a full keyboard definition myself, but I don't know how & there must be a simple way to get this done.

I really need a full, detailed reference to doing this ... including where to find the various directories (I HAVE found the 'Terminal', but that's it !).

Just a link to a doc or wiki would be welcome ... the web searches I've done have given answers that are too cryptic for my level.

TIA.

I want to modificate a Linux distro but i haven't knowledge for this.
What i want to do is put it in a machine and let it in a public place. It should have keyboard so people can type the things as they want. But i cant allow shortcuts, terminal or tty to be opened by this keyboard. I am thinking about 2 keyboards with different permissions. To the mouse my idea is touchscreen.I should also make a good gui so it can be more pleasant to the people. And as the idea grows i want to add more features. But i really lack knowledge to do so. Could someone give me tips of books to guide me trough this path?

Hi, all! So I am taking a Linux O/S class for my degree requirements. The book we are using is "Linux Bible" - 8th ed. by Christopher Negus. Per our instructor, I am accessing Fedora via Oracle VM VirtualBox. Negus refers to a Windows keyboard when he instructs us to enter, for example, Ctrl+Alt+F2 to open a virtual console. Where can I find a list of MAC keyboard equivalent key combos or will I have to assign them myself?

My instructor was no help with this question and told me I would have to scour the Internet which i have to no avail.

I have an assignment due and I can't follow along until I figure this out. Any help would be appreciated.

Wireless mouse and wireless keyboard is not working in Linux distro's.

Read the similar threads on this issue. Boot mode is set for UEFI and Legacy therefore not sure what to do to enable mouse and keyboard? The mouse and keyboard use the same 'receiver' and the receiver indicator is green when Linux distro is fully loaded. Have tried various distro's, Ubuntu, and Ubuntu based distro's using LIVE DVD method on all. Latest distro tried is Peach 14.04.1 TW.40 64 bit. Motherboard is a Gigabyte GA-990FXA-UD3, CPU AMD FX6300 3.5 Ghz six core.

Thanks for any assistance.

Hello.
I added another language to my Keyboard layout but it is not changed automatically. For example, when I'm in Libreoffice and changed my Keyboard layout to another language and back to Mozillia firefox it is not back to "EN" automatically and I should change it manually.

I use Debian 7.7.

Tnx.

I am new to drivers development under linux kernel. After starting with the simple examples from the book Linux Device Drivers v3, I realised that the block driver API has been totally changed since the kernel 2.6.31 or maybe later versions, and I couldn't find any documentation about the new API and how to use it. There are just some few comments in the source code.

After struggling for one month I almost had something working but few parts are missing or I misunderstood something.

Here is the situation :

After fetching the request with blk_fetch_request(q), I use the macro __rq_for_each_bio for handling the full request
To transfer the segments one by one I use the macro bio_for_each_segment(bvec, bio, i) that loops over all the segments in a bio

My question is :

I need to do some DMA from/to my device (the dma engine is within the device), that's why I need some address that I could use it to DMA from/to
Which buffer should I use ? for the moment I use the buffer returned by char *buffer=bio_data(bio), Does "buffer" corresponds to the physical buffer that I can use for DMA
How to end the request in this case ? using __blk_end_request_cur(req, 0) ? or using __blk_end_request(req, 0, bytes) ?

If you don't have an answer to any of these questions, where can I find a useful documentation for the new API of the block device drivers.

we do have a record buffer in awk utility that holds one complete record of a data file.

I want to know that if record buffer changes during script processing, then when are these changes reflected back to the data file?

Are they reflected immediately or is there an in-built mechanism available to schedule this change?
