It's the ibus...something. No idea what this does¹, but disabling/uninstalling this does the trick. 1) I know, there is documentation...

You can buy all of the above today, in keyboards ranging from about $60 to $450. I had in mind a boxful of Logitech and Kessington keyboards purchased several years ago, as well as two Cherry purchased last year. The Cherry specifications gave me high hopes regarding Cherry, and I paid a good price for the Cherry; but the switches of two of the three I purchased new are beginning to fail. The old IBM you mention, of course, is of the category I mentioned, a design of another era. As to keystroke specifications, I must question current test procedures. In years past, I have experienced key plunger binding long before contact failure was evident. Plunger design does not always take into account the reality of lateral force on the keycap. The application of lubricant is no substitute for proper material selection regarding plunger and tube or body. Nowadays, contact failure seems to be the primary failure mode. Many factors must be considered in the design of a keyswitch. Only with a warranty which provides advance replacement with no-charge delivery and return would I consider paying much over a hundred dollars for a keyboard. When the cost of return shipping by UPS, FEDEX, or USPS is taken into account, a lifetime warranty on a $25 or $50 keyboard is meaningless. RLH

The problem most likely is oxidation of the electrical contacts of the key switch. The silver or gold plating of the contact surfaces may be compromised by mechanical wear. Back in the 1970's, keyswitches were rated in terms of tens of millions or hundreds of millions of keystrokes; keyswitches of today are rated in terms of tens of thousands or hundreds of thousands of keystrokes. Search and read the manufacturer specification sheets for keyswitches. A factor which exacerbates the situation is the ongoing effort to reduce energy consumption; nowadays voltages across keyswitch contacts can be too low to break through oxidation and the currents flowing through contacts may be too low to burn off the oxidation. Research years ago by Honeywell Corporation revealed that gold-plated contacts are not always a good approach. Though gold does not oxidize, the presence of oil vapour in the atmosphere can result in formation of an insulating polymer on gold contact surfaces. Silver contacts appear to be the proper approach; silver oxide is conductive. Mechanic design of the contacts also is a factor; when the contacts are bars or rods which cross at an angle, the contact pressure is higher pressure than if the contacts are in the shape of buttons. The pressure helps break through oxidation. Some manufacturers offer "lifetime" keyboards; but the lifetime in view appears to be that of the keyboard and not of the user. Keyboards today can have a useful lifetime measured in months. Much depends upon the environment in which the keyboard is used, particularly the atmospheric humidity. The proper approach to the problem of low voltage and low current would be to design keyboards in which the keyswitch contact voltage and current are an order-of-magnitude higher than the voltage and current of the logic circuitry.

Now one qq press and then a gives á? Double press of qq now results in ´? The latter is the normal behaviour of my Gerrman keyboard layout. For me it's useful because in a Spanish-speaking country I often need the accented characters. This is with layout "German (dead grave acute)". You need to install "German (eliminate dead grave acute)" in your X-setup. I don't know about xfce but for me it is enough to change this in the KDE setup. For programming and for the shell the behaviour with a single-press ´ is better of course. I have no idea why this may have changed. Maybe look through the upgrade protocolls of apt, if you want to know what happened. If you have more than one keyboard layout installed (as I have) then a certain key-combination might have changed it unadvertently.

Well, in lightdm/xfce4-settings this was working with generic German PC 105 keys without further options.

May be silly question, but: Lost my qq(´) and qq(´) key
Hi list, since a few days, my qq(´) and qq(´)¹ don't work with a single press. I have to press twice. Who can tell me why? And, ho do I get my old single press behavior back? Sorry I don't get this keyboard magic in this life... 1) On a German keyboard, it is the key left of the backspace. Thanks, Martin
