Half of the businesses that have deployed Linux on the desktop have rolled it out to less than 20% of their workers, according to analyst firm Freeform Dynamics.
One in five organisations adopting Linux on the desktop have, though, rolled it out to 80% of their staff, according to the survey which is sponsored by Linux supporter IBM.
Many organisations are limiting Linux deployment because of perceived and real obstacles, according to Freeform Dynamics. Power users in the office, mobile professionals and creative types such as graphic designers were the least likely to accept Linux on their PCs, according to Freeform.
Freeform surveyed 1,275 IT professionals in April, of whom 90% had first-hand experience rolling out Linux at a company. Because of its sample, Freeform cautions that its statistics do not represent most companies, nor do they imply any major gain by Linux on the desktop.
Linux's overall share of desktops remains about 1%, according to figures released last month by Net Applications.
IBM hopes to boost that. With Ubuntu Linux vendor Canonical Inc., it offers a "Microsoft-free" desktop package that includes its Lotus desktop applications.
According to the survey, 70% of those deploying Linux inside businesses cited lower cost as the primary driver. Rather than the price of licensing Microsoft Corp.'s Windows for enterprises, more than half of respondents cited the ease of securing Linux PCs as the main reason for its lower cost relative to Windows.
Respondents also cited more flexible deployment of Linux as well as less need for support and administration.
But there are many obstacles to deploying Linux, according to respondents: internal politics, user resistance to switching from Windows, and the lack of compatible software for Linux were cited as major roadblocks by more than half of those surveyed.
While employees "might occasionally moan and groan about Windows, it is an environment they are used to which largely does the job, and the fear is that any change will be painful and distracting," according to Freeform.
"There is also the question of consistency between the work environment and the software used at home, which is overwhelmingly Windows based. Against this background, the Linux option is sometimes considered to be the 'techie' alternative which, even without any direct experience, is often dismissed as not being appropriate for normal users."
Freeform concludes that the best strategy is limited rollouts of Linux targeted at the employee populations most likely to accept the open-source operating system.
These include developers and IT pros can handle the transition to Linux the easiest, according to the surveyed, followed by general office workers.
For other employees, "be prepared, however, to find that it is simply not cost-effective to switch some users from Windows, either from an IT or business perspective," the firm wrote.
